ADS8321E from Texas Instruments, in a VSSOP-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 accepting 0.5V to VCC/2 with 5GΩ input impedance for setting analog input full-scale range |
| 2 | +In | input | Non-inverting analog input with absolute voltage range GND - 0.3V to VCC + 0.3V |
| 3 | -In | input | Inverting analog input with absolute voltage range GND - 0.3V to 4V |
| 4 | GND | power_in | Ground return connection |
| 5 | CS/SHDN | input | Chip Select when LOW to initiate conversion; Shutdown when HIGH reducing supply current to 3µA max |
| 6 | DOUT | tri_state | Serial data output tri-state, 16-bit conversion result shifted MSB first on falling DCLOCK edges |
| 7 | DCLOCK | input | Data Clock input with frequency range 24kHz to 2.4MHz for synchronizing serial data transfer |
| 8 | +VCC | power_in | Power supply input, 4.75V to 5.25V for specified performance |
