TDA2822L-D08-T from UTC Unisonic Tech, 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 | OUTPUT1 | output | Channel 1 amplifier output; peak output current is rated at 1 A. |
| 2 | VCC | power_in | Positive supply input; operating range 1.8V to 12V, absolute maximum 15V. |
| 3 | OUTPUT2 | output | Channel 2 amplifier output; peak output current is rated at 1 A. |
| 4 | GND | power_in | Ground connection for the supply and both amplifier channels. |
| 5 | NF2 | input | Channel 2 feedback input (NP2, inverting node of amplifier 2) used to set closed-loop gain. |
| 6 | INPUT2 | input | Channel 2 non-inverting signal input with 100 kOhm typical input resistance. |
| 7 | INPUT1 | input | Channel 1 non-inverting signal input with 100 kOhm typical input resistance. |
| 8 | NF1 | input | Channel 1 feedback input (NP1, inverting node of amplifier 1) used to set closed-loop gain. |
