AD4150B from IDCHIP, in a MSOP-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 input: high level for normal operation, low level stops the chip (shutdown current 0.2 µA typ); must be held at a stable voltage. |
| 2 | BYP | passive | Bias voltage (VDD/2) output; connect a 0.1 µF to 1 µF bypass capacitor CB (1 µF or larger recommended). |
| 3 | NC | unconnected | No function; the datasheet states pin 3 has no function (typical circuit ties it to the BYP net). |
| 4 | INN | input | Analog inverting input; gain set by external input resistor Ri via AVD=2*(120K/Ri), with input coupling capacitor Ci. |
| 5 | VO1 | output | Analog output 1 of the bridge-tied load amplifier, connected to one speaker terminal. |
| 6 | VDD | power_in | Positive power supply, 1.8V to 5.5V operating range, with decoupling capacitor close to the pin. |
| 7 | GND | power_in | Power ground. |
| 8 | VO2 | output | Analog output 2 of the bridge-tied load amplifier, connected to the other speaker terminal. |
