ADS7822U

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

ADS7822U from Texas Instruments, in a SOIC-8. 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 VREF power_in Reference voltage input; acceptable range 50mV to VCC sets the full-scale analog input range.
2 +In input Noninverting analog input; operating range must be maintained within GND-200mV to VCC+200mV for proper linearity.
3 -In input Inverting analog input with operating range of GND-200mV to GND+1.0V; connect to local ground or remote ground sense reference.
4 GND power_in Ground reference for all analog and digital circuits.
5 CS/SHDN input Chip select (active low) that initiates conversion on falling edge; high level activates shutdown mode with 3μA maximum quiescent current.
6 DOUT tri_state Serial data output transmitting 12-bit conversion result MSB-first on DCLOCK falling edge; tri-states when CS is high.
7 DCLOCK input Data clock input synchronizing serial data output; operating frequency range 10kHz to 3.2MHz maximum.
8 +VCC power_in Power supply input with operating range 2.0V to 5.25V; specified performance guaranteed over 2.7V to 5.25V range.
