AD7476BRTZ-R2 from Analog Devices, in a SOT-23-6. 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 | VDD | power_in | Power supply input; the VDD range for the AD7476/AD7477/AD7478 is 2.35 V to 5.25 V. |
| 2 | GND | power_in | Analog ground and ground reference point for all circuitry on the part; all analog input signals should be referred to this GND voltage. |
| 3 | VIN | power_in | Single-ended analog input channel; the input range is 0 V to VDD. |
| 4 | SCLK | input | Logic input that provides the serial clock for accessing data from the part and is also the clock source for the conversion process. |
| 5 | SDATA | output | Logic output that provides the conversion result as a serial data stream, with bits clocked out on the falling edge of SCLK, MSB first. |
| 6 | CS | input | Active-low logic input that initiates conversions and frames the serial data transfer. |
