ADS7822UC

Texas Instruments · Analog To Digital Converters (ADC) · SOIC-8

ADS7822UC 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; the reference voltage can be set to any level from 50 mV up to VCC.
2 +In input Noninverting analog input; the absolute input range is -0.2 V to VCC + 0.2 V relative to GND.
3 -In input Inverting analog input; connect to ground or to a remote ground sense point, with an absolute input range of -0.2 V to +1.0 V relative to GND.
4 GND power_in Ground reference for the device.
5 CS/SHDN input Chip select when low; shutdown mode when high.
6 DOUT output Serial output data word of 12 bits, valid on the falling edge of DCLOCK; the output is enabled by the second clock pulse after CS falls, followed by one null bit.
7 DCLOCK input Data clock that synchronizes the serial data transfer and determines the conversion speed.
8 +VCC power_in Power supply; specified at 2.7 V to 3.6 V and 4.75 V to 5.25 V, with an absolute maximum of +6 V.
