TDA7052AG-S08-R from UTC Unisonic Tech, in a SOP-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 | VP | power_in | Positive power supply input, rated 4.5 V to 18 V (absolute maximum 18 V) with total quiescent current of 7 mA typical and 12 mA maximum at VP=6 V and RL open. |
| 2 | IN+ | input | Signal input terminal with an input impedance of 15 to 25 kΩ, and an absolute maximum input voltage of 8 V. |
| 3 | GND1 | power_in | Signal ground reference for the input and volume-control circuitry, to be kept separate from the power ground on pin 6. |
| 4 | VC | input | DC volume control terminal with a control current of 70 to 80 µA at V4=0.4 V, mute at V4 ≤ 0.3 V, and an absolute maximum voltage of 8 V. |
| 5 | OUT+ | output | Non-inverted BTL loudspeaker output, part of the bridge output pair that delivers 1.1 W into 8 Ω at 10% THD with a 18 V maximum supply and 1.25 A repetitive peak output current. |
| 6 | GND2 | power_in | Power ground for the output stage, carrying the output current return path. |
| 7 | NC | unconnected | Not connected internally; labelled n.c. in the block diagram. |
| 8 | OUT- | output | Inverted BTL loudspeaker output, the complementary bridge output to OUT+ with a 1.25 A repetitive peak output current limit. |
