ADS7822EC

Texas Instruments · Analog To Digital Converters (ADCs) · MSOP-8

ADS7822EC from Texas Instruments, in a MSOP-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 input Reference input. Sets the ADC full-scale range; may be driven from 50mV up to VCC.
2 +In input Noninverting analog input to the pseudo-differential sample-and-hold. Absolute range -0.2V to VCC+0.2V.
3 -In input Inverting analog input. Connect to ground or to a remote ground sense point; absolute range -0.2V to +1.0V above GND.
4 GND power_in Ground return for both analog and digital supply currents.
5 CS/SHDN input Active-low chip select and shutdown control. Low enables conversion and serial output; high places the device in power-down mode (<3µA typical).
6 DOUT output Serial data output (MISO). 12-bit conversion word clocked out MSB-first on the falling edge of DCLOCK after CS falls; data valid for the next edge after one null bit.
7 DCLOCK input External serial data clock (SCLK). Synchronizes the serial data transfer and determines the conversion speed; fCLK = 16 x fSAMPLE.
8 +VCC power_in Positive supply input, 2.7V to 5.25V (operational from 2.0V). Bypass to GND with a local decoupling capacitor.

  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: ads7822ec-etched.step / ads7822ec-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ads7822ec.step / ads7822ec.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (31 pp, sha256 889c901a1116a5b2, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
