ADS7829IDRBR from Texas Instruments, in a SON-8-EP(3x3). 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 | Vref | power_in | Reference input; the reference voltage range is 0.05 V to VCC - 0.2 V for 2.7 V ≤ VCC ≤ 3.6 V. |
| 2 | +In | input | Noninverting analog input; the absolute input range is -0.2 V to VCC + 0.2 V. |
| 3 | -In | input | Inverting analog input, to be connected to ground or to a remote ground sense point; the absolute input range is -0.2 V to 1.0 V. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | CS/SHDN | input | Chip select when LOW and shutdown mode when HIGH. |
| 6 | DOUT | output | Serial output carrying a 12-bit data word that is valid on the falling edge of DCLOCK; the serial output is enabled by the second clock pulse after the falling edge of CS, followed by one null bit and then 12 data edges. |
| 7 | DCLOCK | input | Data clock that synchronizes the serial data transfer and determines the conversion speed. |
| 8 | +VCC | power_in | Power supply; operating range is 2.7 V to 3.6 V, with reduced performance down to 2.0 V and operation to 5.25 V stated in the electrical specifications. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
