LM2904QDRQ1

Texas Instruments · Operational Amplifier · SOIC-8

LM2904QDRQ1 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 the first operational amplifier; voltage swing approaches V- and V+ supply rails depending on load current and output impedance.
2 IN1- input Negative input of the first operational amplifier; common-mode input range (V-) to (V+) - 1.5V.
3 IN1+ input Positive input of the first operational amplifier; common-mode input range (V-) to (V+) - 1.5V.
4 V- power_in Negative power supply or ground reference for single-supply operation; establishes minimum voltage reference for all measurements.
5 IN2+ input Positive input of the second operational amplifier; common-mode input range (V-) to (V+) - 1.5V.
6 IN2- input Negative input of the second operational amplifier; common-mode input range (V-) to (V+) - 1.5V.
7 OUT2 output Output of the second operational amplifier; voltage swing approaches V- and V+ supply rails depending on load current and output impedance.
8 V+ power_in Positive power supply; operating range 3V to 26V for LM2904-Q1.
