LM2904AYDT from STMicroelectronics, in a SOIC-8. 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; swings 0 V to (VCC+ − 1.5 V), typical source current 40 mA max, sink current 20 mA typ at VCC+ = 5 V. |
| 2 | IN1- | input | Inverting input of amplifier 1; common-mode range 0 V to (VCC+ − 1.5 V), input bias current 20 nA typ / 150 nA max at 25 °C. |
| 3 | IN1+ | input | Non-inverting input of amplifier 1; common-mode range 0 V to (VCC+ − 1.5 V), input offset current 2 nA typ / 30 nA max at 25 °C. |
| 4 | VCC- | power_in | Negative supply / ground reference; all voltages on the device are referenced to this terminal. |
| 5 | IN2+ | input | Non-inverting input of amplifier 2; common-mode range 0 V to (VCC+ − 1.5 V), input bias current 20 nA typ / 150 nA max at 25 °C. |
| 6 | IN2- | input | Inverting input of amplifier 2; common-mode range 0 V to (VCC+ − 1.5 V), input offset current 2 nA typ / 30 nA max at 25 °C. |
| 7 | OUT2 | output | Output of amplifier 2; swings 0 V to (VCC+ − 1.5 V), typical source current 40 mA max, sink current 20 mA typ at VCC+ = 5 V. |
| 8 | VCC+ | power_in | Positive supply; operating range 3 V to 30 V, total supply current 0.7 mA typ / 1.2 mA max for both amplifiers with no load at VCC+ = 5 V and 25 °C. |
