# LM2904BIDGKR

**Texas Instruments** · Operational Amplifier · VSSOP-8

LM2904BIDGKR from Texas Instruments, in a VSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT1 | output | Output of op-amp channel 1. Push-pull class-AB output stage capable of sinking to within a few mV of V- and sourcing up to (V+ - 1.5 V) typical. |
| 2 | IN1- | input | Inverting input of op-amp channel 1. High-impedance input; PNP input stage allows the common-mode range to include V- (ground in single-supply operation). |
| 3 | IN1+ | input | Non-inverting input of op-amp channel 1. High-impedance input; common-mode range includes V- (ground). |
| 4 | V- | power_in | Negative supply (or GND in single-supply operation). Supply range V+ - V- = 3 V to 36 V for the B variant (absolute max ±20 V or 40 V). |
| 5 | IN2+ | input | Non-inverting input of op-amp channel 2. High-impedance input; common-mode range includes V- (ground). |
| 6 | IN2- | input | Inverting input of op-amp channel 2. High-impedance input; common-mode range includes V- (ground). |
| 7 | OUT2 | output | Output of op-amp channel 2. Push-pull class-AB output stage capable of sinking to within a few mV of V- and sourcing up to (V+ - 1.5 V) typical. |
| 8 | V+ | power_in | Positive supply. Operating range 3 V to 36 V (relative to V-); quiescent current typically 300 μA per amplifier. |
