19-1224; Rev 3; 1/0 7 High-Output-Drive, Precision, Low-Power, SingleSupply, Rail-to-Rail I/O Op Amps with Shutdown The MAX4165-MAX4169 family of operational amplifiers combines excellent DC accuracy with high output current drive, single-supply operation, and rail-to-rail inputs and outputs. These devices operate from a single +2.7V to +6.5V supply, or from dual 1.35V to 3.25V supplies. They typically draw 1.2mA supply current, and are guaranteed to deliver 80mA output current. The MAX4166/MAX4168 have a shutdown mode that reduces supply current to 38A per amplifier and places the outputs into a high-impedance state. The MAX4165-MAX4169's precision performance combined with high output current, wide input/output dynamic range, single-supply operation, and low power consumption makes them ideal for portable audio applications and other low-voltage, battery-powered systems. The MAX4165 is available in the space-saving 5-pin SOT23 package and the MAX4166 is available in a tiny 2mm x 2mm x 0.8mm DFN package.

As a general rule, as long as the peak current is less than or equal to 80mA, the maximum package power dissipation will not be exceeded for any of the package types offered. There are some exceptions to this rule, however. The absolute maximum power-dissipation rating of each package should always be verified using the following equations. The following equation gives an approximation of the package power dissipation: R C VIN = 3Vp-p MAX4165 MAX4166 R 60 PIC(DISS) VRMS IRMS COS where: VRMS = the RMS voltage from VCC to VOUT when sourcing current = the RMS voltage from V OUT to V EE when sinking current IRMS = the RMS current flowing out of or into the op amp and the load = the phase difference between the voltage and the current. For resistive loads, COS = 1. For example, the circuit in Figure 1 has a package power dissipation of 157mW. V VRMS VCC - VDC - PEAK 2 1.5V = 6.5V - 3.25V - = 2.189VRMS 2 I 3.25V 1.5V / 60 IRMS IDC + PEAK = + 60 2 2 ( Figure 1. A Circuit Example where the MAX4165/MAX4166 is Being Used in Single-Supply Operation 6.5V R C VIN = 3Vp-p CC R MAX4165 MAX4166 ) = 71.84mARMS Therefore, PIC(DISS) = VRMS IRMS COS = 157mW Adding a coupling capacitor improves the package power dissipation because there is no DC current to the load, as shown in Figure 2.

Dual MAX4167/MAX4168 Bridge Amplifier for 200mW at 3V MAX4165 MAX4166 MAX4167 MAX4168 MAX4169 Single-Supply Speaker Driver The MAX4165/MAX4166 can be used as a single-supply speaker driver, as shown in the Typical Operating Circuit. Capacitor C1 is used for blocking DC (a 0.1F ceramic capacitor can be used). When choosing resistors R3 and R4, take into consideration the input bias current as well as how much supply current can be tolerated. Choose resistors R1 and R2 according to the amount of gain and current desired. Capacitor C3 ensures unity gain for DC. A 10F electrolytic capacitor is suitable for most applications. The coupling capacitor C2 sets a low-frequency pole and is fairly large in value. For a 32 load, a 100F coupling capacitor gives a low-frequency pole at 50Hz. The low-frequency pole can be set according to the following equation: = 1 / 2 (RLC2) Bridge Amplifier The circuit shown in Figure 3 uses a dual MAX4167/ MAX4168 to implement a 3V, 200mW amplifier suitable for use in size-constrained applications. This configuration eliminates the need for the large coupling capacitor required by the single op-amp speaker driver when single-supply operation is a must. Voltage gain is set to +10V/V; however, it can be changed by adjusting the 900k resistor value. DC voltage at the speaker is limited to 10mV. The 47 and 0.1F capacitors across the speaker maintain a low impedance at the load as frequency increases. 10 R3 R3 = R1 R2 R1 R2 Figure 5. Reducing Offset Error Due to Bias Current (Inverting) Rail-to-Rail Input Stage Devices in the MAX4165-MAX4169 family of high-output-current amplifiers have rail-to-rail input and output stages designed for low-voltage, single-supply operation. The input stage consists of separate NPN and PNP differential stages that combine to provide an input common-mode range that extends 0.25V beyond the supply rails. The PNP stage is active for input voltages close to the negative rail, and the NPN stage is active for input voltages near the positive rail. The switchover transition region, which occurs near VCC / 2, has been extended to minimize the slight degradation in common-mode rejection ratio caused by mismatch of the input pairs. ______________________________________________________________________________________ High-Output-Drive, Precision, Low-Power, SingleSupply, Rail-to-Rail I/O Op Amps with Shutdown MAX4165-MAX4169 1k 1k Since the input stage switches between the NPN and PNP pairs, the input bias current changes polarity as the input voltage passes through the transition region. Match the effective impedance seen by each input to reduce the offset error caused by input bias currents flowing through external source impedances (Figures 4 and 5). High source impedances, together with input capacitance, can create a parasitic pole that produces an underdamped signal response. Reducing the input impedance or placing a small (2pF to 10pF) capacitor across the feedback resistor improves response. The MAX4165-MAX4169's inputs are protected from large differential input voltages by 1k series resistors and back-to-back triple diodes across the inputs (Figure 6). For differential voltages less than 1.8V, input resistance is typically 500k. For differential input voltages greater than 1.8V, input resistance is approximately 2k. The input bias current is given by the following equation: IBIAS = (VDIFF - 1.8V) / 2k Rail-to-Rail Output Stage The minimum output is within millivolts of ground for single-supply operation, where the load is referenced to ground (VEE). Figure 7 shows the input voltage range and the output voltage swing of a MAX4165 connected as a voltage follower. The maximum output voltage swing is load dependent; however, it is guaranteed to be within 430mV of the positive rail (VCC = 5V) even with maximum load (25 to ground). MAX4165-fig07 Figure 6.

Rail-to-Rail Input/Output Range Driving Capacitive Loads The MAX4165-MAX4169 have a high tolerance for capacitive loads. They are stable with capacitive loads up to 250pF. Figure 8 is a graph of the stable operating region for various capacitive loads vs. resistive loads. Figures 9 and 10 show the transient response with excessive capacitive loads (1500pF), with and without the addition of an isolation resistor in series with the output. Figure 11 shows a typical noninverting capacitive-load-driving circuit in the unity-gain configuration. The resistor improves the circuit's phase margin by isolating the load capacitor from the op amp's output. ______________________________________________________________________________________ 11 CAPACITIVE LOAD (pF) VCC = +5.0V RL to VCC / 2 OUT (20mV/div) STABLE REGION 100 VCC = +3.0V, CL = 1500pF RL = 100k, RISO = 0 IN (20mV/div) UNSTABLE REGION 10 MAX4165-fig09 MAX4165-fig08 1300 1200 1100 1000 900 800 700 600 500 400 300 200 100 0 1k 10k 100k TIME (1s/div) RESISTIVE LOAD (k) Figure 8.

Small-Signal Transient Response with Excessive Capacitive Load with Isolation Resistor Power-Up and Shutdown Modes The MAX4166/MAX4168 have a shutdown option. When the shutdown pin (SHDN) is pulled low, supply current drops to 58A per amplifier (VCC = +5V), the amplifiers are disabled, and their outputs are placed in a high-impedance state. Pulling SHDN high or leaving it floating enables the amplifier. In the dual MAX4168, the two amplifiers shut down independently. Figures 12 and 13 show the MAX4166's output voltage and supply-current responses to a shutdown pulse. The MAX4166-MAX4169 typically settle within 5s after power-up (Figure 14). 12 Figure 11. Capacitive-Load-Driving Circuit Power Supplies and Layout The MAX4165-MAX4169 can operate from a single +2.7V to +6.5V supply, or from dual 1.35V to 3.25V supplies. For single-supply operation, bypass the power supply with a 0.1F ceramic capacitor in parallel with at least 1F. For dual-supply operation, bypass each supply to ground. Good layout improves performance by decreasing the amount of stray capacitance at the op amps' inputs and outputs. Decrease stray capacitance by placing external components close to the op amps' pins, minimizing trace and lead lengths. ______________________________________________________________________________________ SHDN (1V/div) MAX4165-fig13 MAX4165-MAX4169 MAX4165-fig12 High-Output-Drive, Precision, Low-Power, SingleSupply, Rail-to-Rail I/O Op Amps with Shutdown SHDN (1V/div) ICC (1mA/div) OUT (1V/div) TIME (5s/div) TIME (50s/div) Figure 13.
