LM2904P from Texas Instruments, in a DIP-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; the swing is specified relative to the supply rails (for example, 1.35 V to 1.42 V below V+ at 50 µA source current). |
| 2 | IN1- | input | Inverting input of amplifier 1; the recommended common-mode voltage range is V- to V+ − 2 V. |
| 3 | IN1+ | input | Non-inverting input of amplifier 1; the recommended common-mode voltage range is V- to V+ − 2 V. |
| 4 | V- | power_in | Negative (lowest) supply rail, or ground for single-supply operation; the LM2904 recommended total supply is 3 V to 26 V. |
| 5 | IN2+ | input | Non-inverting input of amplifier 2; the recommended common-mode voltage range is V- to V+ − 2 V. |
| 6 | IN2- | input | Inverting input of amplifier 2; the recommended common-mode voltage range is V- to V+ − 2 V. |
| 7 | OUT2 | output | Output of amplifier 2; the swing is specified relative to the supply rails. |
| 8 | V+ | power_in | Positive (highest) supply rail; the LM2904 absolute maximum supply is 26 V (±13 V split supply), with recommended operation at 3 V to 26 V. |
