The LMV3XX family is designed to operate from 2.7 V (1.35 V) to 5.5 V (2.75 V) supplies. The common mode voltage range extends below the negative rail and the output provides rail-to-rail performance. The LMV3XX family is designed on a CMOS process and provides 1.2 MHz of bandwidth and 1.5 V/s of slew rate at a low supply voltage of 2.7 V. The combination of low power, rail-to-rail performance, low voltage operation, and tiny pack-age options make the LMV3XX family well suited for use in personal electronics equipment such as cellular handsets, pagers, PDAs, and other battery powered applications.

The LMV3XX family is fabricated on a CMOS process, features a railto-rail output, and is unity gain stable. The typical non-inverting circuit schematic is shown in Figure1. +Vs Rs LMV3XX - CL 10k 2k 10k Figure 2.

Typical Non-inverting configuration Figure 3. Frequency Response vs. CL for unity gain configuration Power Dissipation The maximum internal power dissipation allowed is directly related to the maximum junction temperature. If the maximum junction temperature exceeds 150C, some performance degradation will occur. If the maximum junction temperature exceeds 175C for an extended time, device failure may occur. Driving Capacitive Loads The Frequency Response vs. CL plot on page 4, illustrates the response of the LMV3XX family. A small series resistance (RS) at the output of the amplifier, illustrated in Figure 2, will improve stability and settling performance. Rs values in the Frequency Response vs. CL plot were chosen to achieve maximum bandwidth with less than 1dB of peaking. For maximum flatness, use a larger RS. As the plot indicates, the LMV3XX family can easily drive a 200 pF capacitive load without a series resistance. For comparison, the plot also shows the LMV321 driving a 200 pF load with a 225 series resistance. Driving a capacitive load introduces phase-lag into the output signal, which reduces phase margin in the amplifier. The unity gain follower is the most sensitive configuration. In a unity gain follower configuration, the LMV3XX family requires a 450 series resistor to drive a 200 pF load. The response is illustrated in Figure 3. Layout Considerations General layout and supply bypassing play major roles in high frequency performance. ON Semiconductor has evaluation boards to use as a guide for high frequency layout and as aid in device testing and characterization. Follow the steps below as a basis for high frequency layout: * Include 6.8 F and 0.01 F ceramic capacitors * Place the 6.8 F capacitor within 0.75 inches of the power pin * Place the 0.01 F capacitor within 0.1 inches of the power pin * Remove the ground plane under and around the part, especially near the input and output pins to reduce parasitic capacitance * Minimize all trace lengths to reduce series inductances Refer to the evaluation board layouts shown in Figure 5 on page 8 for more information. www.onsemi.com 8 LMV321 / LMV358 / LMV324 -- General-Purpose, Low Voltage, Rail-to-Rail Output Amplifiers Application Information The following evaluation boards are NOT available any more but their Schematic & Layout information will be useful for references to aid in the testing and layout of this device.
