LM2904AVQDRQ1

Texas Instruments · Operational Amplifier · SOIC-8

LM2904AVQDRQ1 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 1OUT output Output of amplifier 1. Class-B push-pull output driven by an internal ~50 µA sink current regulator; can sink/source loads referenced to GND with V_OL ≈ 5 mV at R_L ≥ 10 kΩ.
2 1IN- input Inverting input of amplifier 1. Differential input voltage rating ±32 V (V-suffix); typical input bias current -20 nA, input offset current 2 nA typ.
3 1IN+ input Non-inverting input of amplifier 1. Common-mode input voltage range includes ground (0 V to V_CC-1.5 V), enabling direct sensing near GND on single-supply rails.
4 GND power_in Negative supply / ground reference (V_CC-). Tie to system ground for single-supply operation, or to the negative rail for split-supply operation (V_CC - GND up to 32 V for V-suffix parts).
5 2IN+ input Non-inverting input of amplifier 2. Common-mode input voltage range includes ground (0 V to V_CC-1.5 V).
6 2IN- input Inverting input of amplifier 2. Differential input voltage rating ±32 V (V-suffix); input bias current -20 nA typ.
7 2OUT output Output of amplifier 2. Same class-B output stage as 1OUT; short-circuit output current ±40 mA typ at V_CC = 5 V.
8 VCC power_in Positive supply rail. 3 V to 32 V for V-suffix devices (3 V to 26 V for non-V), shared by both amplifiers; total quiescent current 0.7 mA typ, 1.2 mA max.
