LM2904BQDRQ1

Texas Instruments · Operational Amplifier · SOIC-8

LM2904BQDRQ1 from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT1 output Output of op-amp channel 1. Class-AB push-pull stage, capable of sinking/sourcing typical short-circuit current; output swings from V- (rail-to-rail low) to within about 1.5 V of V+.
2 IN1- input Inverting (negative) input of op-amp channel 1. High-impedance PNP input; common-mode input range extends down to V-.
3 IN1+ input Non-inverting (positive) input of op-amp channel 1. High-impedance PNP input; common-mode input range extends down to V-.
4 V- power_in Negative (most negative) supply rail, or GND for single-supply operation. Total supply voltage V+ to V- must be 3 V to 36 V (LM2904B/BA-Q1).
5 IN2+ input Non-inverting (positive) input of op-amp channel 2. High-impedance PNP input; common-mode input range extends down to V-.
6 IN2- input Inverting (negative) input of op-amp channel 2. High-impedance PNP input; common-mode input range extends down to V-.
7 OUT2 output Output of op-amp channel 2. Class-AB push-pull stage; output swings from V- (rail-to-rail low) to within about 1.5 V of V+.
8 V+ power_in Positive (most positive) supply rail. Absolute range 3 V to 36 V referenced to V- for LM2904B-Q1 / LM2904BA-Q1.
