ADS7822U from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VREF | power_in | Reference voltage input; acceptable range 50mV to VCC sets the full-scale analog input range. |
| 2 | +In | input | Noninverting analog input; operating range must be maintained within GND-200mV to VCC+200mV for proper linearity. |
| 3 | -In | input | Inverting analog input with operating range of GND-200mV to GND+1.0V; connect to local ground or remote ground sense reference. |
| 4 | GND | power_in | Ground reference for all analog and digital circuits. |
| 5 | CS/SHDN | input | Chip select (active low) that initiates conversion on falling edge; high level activates shutdown mode with 3μA maximum quiescent current. |
| 6 | DOUT | tri_state | Serial data output transmitting 12-bit conversion result MSB-first on DCLOCK falling edge; tri-states when CS is high. |
| 7 | DCLOCK | input | Data clock input synchronizing serial data output; operating frequency range 10kHz to 3.2MHz maximum. |
| 8 | +VCC | power_in | Power supply input with operating range 2.0V to 5.25V; specified performance guaranteed over 2.7V to 5.25V range. |
