# ADS7866IDBVR

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

ADS7866IDBVR from Texas Instruments, in a SOT-23-6. 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 | REF/VDD | power_in | External reference input and power supply operating from 1.2V to 3.6V. |
| 2 | GND | power_in | Ground for signal and power supply, with all analog and digital signals referred with respect to this pin. |
| 3 | VIN | power_in | Analog signal input with 0V to VDD unipolar input range and 12pF input capacitance. |
| 4 | SCLK | input | Serial clock input for controlling conversion rate and shifting data out, with maximum frequency 3.4MHz at VDD≥1.6V or 1.7MHz at VDD≥1.2V. |
| 5 | SDO | tri_state | Serial data output with MSB first, transitioned on falling edge of SCLK after sampling period, and three-stated once all valid bits are clocked out. |
| 6 | CS | input | Active low chip select input used to gate SCLK input, initiate conversion, and frame output data. |
