ADS7817UC from Texas Instruments, in a SOIC-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 | VREF | power_in | Reference input, which the datasheet says can be varied from 100mV to 2.5V. |
| 2 | +In | input | Non-inverting input of the fully differential analog input, with an absolute input voltage range of -0.3V to VCC + 0.3V. |
| 3 | -In | input | Inverting input of the fully differential analog input, with an absolute input voltage range of -0.3V to 4V. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | CS/SHDN | input | Chip select when LOW; places the device in shutdown mode when HIGH. |
| 6 | DOUT | output | Serial output data word of 12 bits, valid on the falling edge of DCLOCK; the second clock pulse after the falling edge of CS enables the output, and after one null bit the data is valid for the next 12 edges. |
| 7 | DCLOCK | input | Data clock that synchronizes the serial data transfer and determines the conversion speed. |
| 8 | +VCC | power_in | Power supply; the absolute maximum rating is +6V and the specified performance range is 4.75V to 5.25V. |
