IDCHIP · Audio Amplifiers · SOP-8
AD8302 from IDCHIP, 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 | SD | input | Shutdown control: a high level keeps the amplifier operating and a low level shuts it down, with VIH min 1.2 V and VIL max 0.9 V, and the pin must not be left floating. |
| 2 | NC | unconnected | No internal connection (empty pin). |
| 3 | BYP | output | Bias voltage output at VDD/2 that requires a bypass capacitor CB, where 0.1 µF to 1 µF ceramic is typical and 1 µF or larger is recommended to limit turn-on noise. |
| 4 | IN | input | Analog audio input whose external input resistor Ri sets the closed-loop gain according to Gain = (2 x 200 kΩ)/(6 kΩ + Ri). |
| 5 | VO1 | output | Analog class-D output 1, which drives the speaker together with VO2 and should be kept under 100 mm of wire without an output filter. |
| 6 | VDD | power_in | Positive supply, with recommended operating range 2.5 V to 6.0 V and absolute maximum 7.0 V. |
| 7 | GND | power_in | Power ground for the device. |
| 8 | VO2 | output | Analog class-D output 2, which forms the differential speaker output with VO1. |
