Input common mode voltage range exceeds either supply by 0.3 V, enhancing ease of use in multitude of applications where previously only inferior devices could be used. Output voltage range extends to within 20 mV of either supply rails, allowing wide dynamic range especially in low voltage applications. Even with low supply current of 650 A/amplifier, output current capability is kept at a respectable 20 mA for driving heavier loads. Important device parameters such as BW, Slew Rate and output current are kept relatively independent of the operating supply voltage by a combination of process enhancements and design architecture.

Both turn-on and turn-off characteristics are well behaved with minimal output fluctuations during transitions. This allows the part to be used in power saving mode, as well as multiplexing applications. Miniature packages (SOT-23, VSSOP-8, and SOIC-8) are further means to ease the adoption of these low power high speed devices in applications where board area is at a premium. 6 Pin Configuration and Functions SOT-23-5 (LMH6645) Package DBV05A Top View SOIC-8 (LMH6645) Package D08A Top View 5 1 OUTPUT V 1 + SOIC-8 and VSSOP-8 (LMH6646) Packages D08A and DGK08A Top View 1 8 N/C 8 + V OUT A N/C A -IN V - 2 7 - + V - 2 + 7 -IN A 2 +IN - + 3 6 + OUT B OUTPUT 3 6 +IN A +IN 4 3 -IN - 4 V SOT-23-6 (LMH6647) Package DBV06A Top View 5 V - 2 + +IN V + N/C 4 5 +IN B -IN +IN 4 1 2 SD - 3 - SOIC-8 (LMH6647) Package D08A Top View 6 1 OUTPUT - + N/C V -IN B B 5 -IN - 3 8 7 - 6 + 4 5 V SD + V OUTPUT N/C Pin Functions PIN NUMBER NAME LMH6645 LMH6646 DBV05A D08A -IN 4 2 +IN 3 3 DGK08A I/O LMH6647 DESCRIPTION DBV06A D08A 4 2 I Inverting input 3 3 I Non-inverting input -IN A 2 I Inverting Input Channel A +IN A 3 I Non-inverting input Channel A -IN B 6 I Inverting input Channel B I Non-inverting input Channel B +IN B 5 N/C OUTPUT 1,5,8 1 6 1 1,5 -- No Connection 6 O Output OUT A 1 O Output Channel A OUT B 7 O Output Channel B SD 5 8 I Shutdown - V 2 4 4 2 4 I Negative Supply V+ 5 7 8 6 7 I Positive Supply Copyright (c) 2001-2014, Texas Instruments Incorporated Product Folder Links: LMH6645 LMH6646 LMH6647 Submit Documentation Feedback 3 LMH6645, LMH6646, LMH6647 SNOS970D - JUNE 2001 - REVISED NOVEMBER 2014 www.ti.com 7 Specifications 7.1 Absolute Maximum Ratings (1) (2) over operating free-air temperature range (unless otherwise noted) MIN MAX Output short circuit duration See VIN differential (3) UNIT (4) and 2.5 V V+ +0.8, V- -0.8 V Supply voltage (V+ - V-) 12.6 V Junction temperature (5) +150 Voltage at input/output pins Soldering Information (1) (2) (3) (4) (5) Infrared or Convection (20 sec) 235 Wave Soldering (10 sec) 260 C Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.

This device family architecture features the following: * Complimentary bipolar devices with exceptionally high ft (8 GHz) even under low supply voltage (2.7 V) and low Collector bias current. * Rail-to-Rail input which allows the input common mode voltage to go beyond either rail by about 0.5 V typically. * A class A-B "turn-around" stage with improved noise, offset, and reduced power dissipation compared to similar speed devices (patent pending). * Common Emitter push-pull output stage capable of 20 mA output current (at 0.5 V from the supply rails) while consuming only 700 A of total supply current per channel. This architecture allows output to reach within mV of either supply rail at light loads. * Consistent performance from any supply voltage (2.7 V to 10 V) with little variation with supply voltage for the most important specifications (BW, SR, IOUT, for example) 8.2 Functional Block Diagram INVERTING INPUT RS 200-400: D4 D1 D3 D2 NON-INVERTING INPUT Figure 42.

The SD pin is "active high" and needs to be tied to V- for normal operation. This input is low current (< 20 A, 4 pF equivalent capacitance) and a resistor to V- ( 20 k) will result in normal operation. Shutdown is ensured when SD pin is 0.4V or less from V+ at any operating supply voltage and temperature. In the shutdown mode, essentially all internal device biasing is turned off in order to minimize supply current flow and the output goes into Hi-Z (high impedance) mode. Complete device Turn-on and Turn-off times vary considerably relative to the output loading conditions, output voltage, and input impedance, but is generally limited to less than 1s (see tables for actual data). As seen in Figure 42 in shutdown, there may be current flow through the internal diodes shown, caused by input potential, if present. This current may flow through the external feedback resistor and result in an apparent output signal. In most shutdown applications the presence of this output is inconsequential. However, if the output is "forced" by another device such as in a multiplexer, the other device will need to conduct the current described in order to maintain the output potential. The total input common mode voltage range, which extends from below V- to beyond V+, is covered by both an NPN and a PNP stage. The NPN stage is switched on whenever the input is less than 1.2 V from V+ and the PNP stage covers the rest of the range. In terms of the input voltage, there is an overlapping region where both stages are processing the input signal. This region is about 0.5 V from beginning to the end. As far as the device application is concerned, this transition is a transparent operation. However, keep in mind that the input bias current value and direction will depend on which input stage is operating (see Figure 29). For low distortion applications, it is best to keep the input common mode voltage from crossing this transition point. Low gain settling applications, which generally encounter larger peak-to-peak input voltages, could be configured as inverting stages to eliminate common mode voltage fluctuations. In terms of the output, when the output swing approaches either supply rail, the output transistor will enter a quasi-saturated state. A subtle effect of this operational region is that there is an increase in supply current in this state (up to 1 mA). The onset of Quasi-saturation region is a function of output loading (current) and varies from 100 mV at no load to about 1 V when output is delivering 20 mA, as measured from supplies. Both input common mode voltage and output voltage level affect the supply current (see Figure 32). With 2.7V supplies and a common mode input voltage range that extends beyond either supply rail, the LMH664x family is well suited to many low voltage/low power applications. Even with 2.7 V supplies, the -3dB BW (@ AV = +1) is typically 55 MHz with a tested limit of 45 MHz. Production testing guarantees that process variations will not compromise speed. This device family is designed to avoid output phase reversal. With input over-drive, the output is kept near the supply rail (or as close to it as mandated by the closed loop gain setting and the input voltage). Figure 45, below, shows the input and output voltage when the input voltage significantly exceeds the supply voltages. The output does not exhibit any phase reversal as some op amps do. However, if the input voltage range is exceeded by more than a diode drop beyond either rail, the internal ESD protection diodes will start to conduct. The current flow in these ESD diodes should be externally limited. 20 Submit Documentation Feedback Copyright (c) 2001-2014, Texas Instruments Incorporated Product Folder Links: LMH6645 LMH6646 LMH6647 LMH6645, LMH6646, LMH6647 www.ti.com SNOS970D - JUNE 2001 - REVISED NOVEMBER 2014 Device Functional Modes (continued) Figure 45 demonstrates that the output is well behaved and there are no spikes or glitches due to the switching.

TI's customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information The LMH664x family is well suited to many low voltage/low power applications and is designed to avoid output phase reversal. Figure 45, for example, depicts the Input/Output Shown with Exceeded Input CMVR and functions as a 2:1 MUX operating on a single 2.7-V power supply by utilizing the shutdown feature of the LMH6647. 9.2 Typical Application 1/5 74HC04 1/5 74HC04 SELECT INPUT 2k 2k 2.7V - SHUTDOWN LMH6647 + INPUT A RL 2.7V SHUTDOWN + INPUT B LMH664 7 - 2k 2k Figure 46. 2:1 MUX Operating off a 2.7V Single Supply 9.2.1 Design Requirements This application requires fast, glitch-less transition between selected channels. The LMH6647 turn on and turn off times are 250 ns and 560 ns respectively. Transition between channels is devoid of any excessive glitches. 9.2.2 Detailed Design Procedure In this application, the LMH6647 output pins are directly tied to each other. The shutdown pin of each LMH6647 is driven in-opposite sense of the other (that is, "Low" on 1st LMH6647 with "High" on the 2nd LMH6647, and vice versa). When shutdown is invoked, the device output enters Hi-Z state, while the alternate LMH6647 is being powered on simultaneously. This way, the shutdown function serves the dual purpose of allowing only the input associated with device which is not in shutdown to be selected and to appear at the output. 22 Submit Documentation Feedback Copyright (c) 2001-2014, Texas Instruments Incorporated Product Folder Links: LMH6645 LMH6646 LMH6647 LMH6645, LMH6646, LMH6647 www.ti.com SNOS970D - JUNE 2001 - REVISED NOVEMBER 2014 Typical Application (continued) 9.2.3 Application Curve Figure 47 shows the MUX output when selecting between a 1 MHz sine and a 250 KHz triangular waveform.

The input CM capability of the parts (CMVR) extends covers the entire supply voltage range for maximum flexibility. Supplies should be decoupled with low inductance, often ceramic, capacitors to ground less than 0.5 inches from the device pins. The use of ground plane is recommended, and as in most high speed devices, it is advisable to remove ground plane close to device sensitive pins such as the inputs.

Parasitic capacitances on these nodes to ground will cause frequency response peaking and possible circuit oscillations. For more information, see Application Note OA-15, Frequent Faux Pas in Applying Wideband Current Feedback Amplifiers (SNOA367). Another important parameter in working with high speed/high performance amplifiers is the component values selection. Choosing large valued external resistors will affect the closed loop behavior of the stage because of the interaction of these resistors with parasitic capacitances. These capacitors could be inherent to the device or a by-product of the board layout and component placement. Either way, keeping the resistor values lower will diminish this interaction. On the other hand, choosing very low value resistors could load down nodes and will contribute to higher overall power dissipation. 11.2 Layout Example Figure 48.
