ADS7816U 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; external voltage (0.1V to 5V) sets full-scale input range. |
| 2 | +In | input | Non-inverting analog input; must remain within GND -0.2V to VCC +0.2V for proper linearity. |
| 3 | -In | input | Inverting analog input; connect to ground or remote ground sense; must stay within ±200mV of GND. |
| 4 | GND | power_in | Ground; analog and logic return reference. |
| 5 | CS/SHDN | input | Chip Select when LOW initiates conversion; HIGH enables power-down mode drawing max 3µA. |
| 6 | DOUT | tri_state | Serial digital output; 12-bit data MSB-first on DCLOCK falling edges, tri-states after conversion complete. |
| 7 | DCLOCK | input | Data Clock input; external clock (10kHz to 3.2MHz) synchronizes serial transfer and sets conversion speed. |
| 8 | +VCC | power_in | Power Supply input; single +5V with specified performance range 4.5V to 5.25V. |
