# ADS7885SDBVR

**Texas Instruments** · Analog To Digital Converters (ADC) · SOT-23-6

ADS7885SDBVR from Texas Instruments, in a SOT-23-6. 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 to the ADC; the datasheet gives a 2.7 V to 5.5 V supply range. |
| 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 that is sampled on the falling edge of CS. |
| 4 | SCLK | input | Serial clock input that drives the conversion and the serial data output. |
| 5 | SDO | output | Serial data output that goes to 3-state when CS is high. |
| 6 | CS | input | Active-low chip select; its falling edge samples VIN and starts the conversion, and a high level aborts an ongoing conversion and puts SDO in 3-state. |
