LM2902QDRG4Q1

Texas Instruments · Operational Amplifier · SOIC-14

LM2902QDRG4Q1 from Texas Instruments, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT1 output Output of channel 1.
2 IN1- input Inverting input of channel 1.
3 IN1+ input Non-inverting input of channel 1.
4 V+ power_in Positive (highest) supply voltage; the datasheet gives VS = (V+) - (V-) = 3 V to 26 V for the LM2902-Q1.
5 IN2+ input Non-inverting input of channel 2.
6 IN2- input Inverting input of channel 2.
7 OUT2 output Output of channel 2.
8 OUT3 output Output of channel 3.
9 IN3- input Inverting input of channel 3.
10 IN3+ input Non-inverting input of channel 3.
11 V- power_in Negative (lowest) supply voltage, or ground for single-supply operation.
12 IN4+ input Non-inverting input of channel 4.
13 IN4- input Inverting input of channel 4.
14 OUT4 output Output of channel 4.
