**Texas Instruments** · Analog To Digital Converters (ADCs) · SC-70-6

ADS7886SBDCKR from Texas Instruments, in a SC-70-6. 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 | VDD | power_in | Power supply input that also acts as the reference voltage for the ADC; the supply range is 2.35 V to 5.25 V. |
| 2 | GND | power_in | Ground for the power supply; all analog and digital signals are referred to this pin. |
| 3 | VIN | power_in | Analog signal input with a unipolar input range of 0 V to VDD. |
| 4 | SCLK | input | Serial clock, used for conversion and for clocking out serial data. |
| 5 | SDO | output | Serial data output. |
| 6 | CS | input | Active-low chip select; the input signal is sampled on the falling edge of CS. |
