LM833MX from Texas Instruments, in a SOIC-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 | OUT A | output | Output of op-amp channel A. Low-impedance audio output capable of driving typical audio loads. |
| 2 | IN A- | input | Inverting input of op-amp channel A. High-impedance differential input. |
| 3 | IN A+ | input | Non-inverting input of op-amp channel A. High-impedance differential input. |
| 4 | V- | power_in | Negative supply rail. Typically -5 V to -18 V for dual-supply operation, or GND for single-supply operation. |
| 5 | IN B+ | input | Non-inverting input of op-amp channel B. High-impedance differential input. |
| 6 | IN B- | input | Inverting input of op-amp channel B. High-impedance differential input. |
| 7 | OUT B | output | Output of op-amp channel B. Low-impedance audio output capable of driving typical audio loads. |
| 8 | V+ | power_in | Positive supply rail. Typically +5 V to +18 V for dual-supply operation, or up to +36 V for single-supply operation. |
