LM2904GD

HTC Korea TAEJIN Tech · Operational Amplifier · SOIC-8-150mil

LM2904GD from HTC Korea TAEJIN Tech, in a SOIC-8-150mil. 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 amplifier 1; the datasheet gives output source current of -30 mA to -50 mA (VCC=15 V, VID=1 V, VO=0 V, 25℃) and sink current of 15 mA to 35 mA (VCC=15 V, VID=-1 V, VO=15 V, 25℃).
2 IN1(-) input Inverting input of amplifier 1; input voltage absolute maximum is -0.3 V to 45 V and input current is limited to 50 mA at VIN = -0.3 V.
3 IN1(+) input Non-inverting input of amplifier 1; common-mode input range is 0 to VCC-1.5 V at 25℃ (0 to VCC-2 V over full temperature range).
4 GND power_in Ground / negative supply reference for the device; the datasheet specifies split-supply operation with VCC- from -1.5 V to -20 V.
5 IN2(+) input Non-inverting input of amplifier 2; common-mode input range is 0 to VCC-1.5 V at 25℃ (0 to VCC-2 V over full temperature range).
6 IN2(-) input Inverting input of amplifier 2; input voltage absolute maximum is -0.3 V to 45 V and input current is limited to 50 mA at VIN = -0.3 V.
7 OUT2 output Output of amplifier 2; the datasheet gives output source current of -30 mA to -50 mA (VCC=15 V, VID=1 V, VO=0 V, 25℃) and sink current of 15 mA to 35 mA (VCC=15 V, VID=-1 V, VO=15 V, 25℃).
8 VCC power_in Positive supply; single-supply range is 3 V to 40 V (absolute maximum 45 V), or VCC+ from +1.5 V to +20 V in split-supply operation.
