LM4808MM from Texas Instruments, in a VSSOP-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 | OUT A | output | Channel A amplifier output, typically AC-coupled to the load through output capacitor Co (e.g. 32Ω load). |
| 2 | IN A (-) | input | Channel A inverting input, connected through input resistor Ri and coupling capacitor Ci, with Rf setting closed-loop gain. |
| 3 | IN A (+) | input | Channel A non-inverting input, biased to 1/2 VDD by the RB divider and bypassed with CB (1.0µF recommended). |
| 4 | GND | power_in | Ground connection for the device. |
| 5 | IN B (+) | input | Channel B non-inverting input, biased to 1/2 VDD by the RB divider and bypassed with CB. |
| 6 | IN B (-) | input | Channel B inverting input, connected through input resistor Ri and coupling capacitor Ci, with Rf setting closed-loop gain. |
| 7 | OUT B | output | Channel B amplifier output, typically AC-coupled to the load through output capacitor Co. |
| 8 | VDD | power_in | Positive supply pin, 2.0V to 5.5V operating range (6.0V absolute maximum), bypassed with a 0.1µF capacitor CS to ground. |
