XC121S101E

Data Acquisition

12-bit ADCSAR ADC800-1000 KSPSSPI serial interfaceSOT-23-63.3-4.8 V

XC121S101E is a 12-bit, single-channel SAR ADC for 800 to 1000 KSPS sampling with a 3.3 V to 4.8 V supply and SPI-compatible serial readout.

Best for

  • Single-channel data acquisition at 800 to 1000 KSPS
  • Low-power portable measurement systems
  • SPI-connected embedded designs

Avoid if

  • More than one analog input channel is required
  • Documented compliance or lifecycle status is mandatory without further verification
  • The host cannot provide 16 serial clock cycles per conversion

Check before use

  • Validate CS and SCLK timing with the host controller
  • Keep the analog input within 0 V to VA
  • Verify supply decoupling placement and compliance requirements
