LM2904VQDR from Texas Instruments, 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 first operational amplifier, output voltage swing from V- + 5mV to V+ - 2V at typical operating conditions. |
| 2 | IN1- | input | Inverting input of first operational amplifier with common-mode input voltage range from V- to V+ - 1.5V. |
| 3 | IN1+ | input | Non-inverting input of first operational amplifier with common-mode input voltage range from V- to V+ - 1.5V. |
| 4 | V- | power_in | Negative power supply rail or ground for single supply operation. |
| 5 | IN2+ | input | Non-inverting input of second operational amplifier with common-mode input voltage range from V- to V+ - 1.5V. |
| 6 | IN2- | input | Inverting input of second operational amplifier with common-mode input voltage range from V- to V+ - 1.5V. |
| 7 | OUT2 | output | Output of second operational amplifier, output voltage swing from V- + 5mV to V+ - 2V at typical operating conditions. |
| 8 | V+ | power_in | Positive power supply rail, operates from 3V to 32V for LM2904V variant. |
