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. |
