1 VOUTA Output Voltage, Channel A. 2 −IN A Negative Input, Channel A. 3 +IN A Positive Input, Channel A. 4 −VS Negative Supply. 5 DISABLE/SELECT A Power-Down/Select, Channel A. The power-down function places the device into low power consumption mode. The select function of this pin shifts the crossover point (where the NPN/PNP input differential pairs transition from one to the other) closer to either the positive supply rail or the negative supply rail. 6 DISABLE/SELECT B Power-Down/Select, Channel B. The power-down function places the device into low power consumption mode. The select function of this pin shifts the crossover point (where the NPN/PNP input differential pairs transition from one to the other) closer to either the positive supply rail or the negative supply rail. 7 +IN B Positive Input, Channel B. 8 −IN B Negative Input, Channel B. 9 VOUTB Output Voltage, Channel B. 10 +VS Positive Supply.
