ADS7817UC

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

ADS7817UC 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, which the datasheet says can be varied from 100mV to 2.5V.
2 +In input Non-inverting input of the fully differential analog input, with an absolute input voltage range of -0.3V to VCC + 0.3V.
3 -In input Inverting input of the fully differential analog input, with an absolute input voltage range of -0.3V to 4V.
4 GND power_in Ground reference for the device.
5 CS/SHDN input Chip select when LOW; places the device in shutdown mode when HIGH.
6 DOUT output Serial output data word of 12 bits, valid on the falling edge of DCLOCK; the second clock pulse after the falling edge of CS enables the output, and after one null bit the data is valid for the next 12 edges.
7 DCLOCK input Data clock that synchronizes the serial data transfer and determines the conversion speed.
8 +VCC power_in Power supply; the absolute maximum rating is +6V and the specified performance range is 4.75V to 5.25V.
