ADC121C021CIMM/NOPB product

ADC121C021CIMM/NOPB

Analog to Digital Converters (ADC)

12-bit ADCSAR ADCI2CVSSOP-8Alert outputVoltage monitoring

ADC121C021CIMM/NOPB is a 12-bit, single-channel SAR ADC for 2.7 V to 5.5 V systems requiring an I2C interface, programmable alert thresholds, and an 8-pin VSSOP footprint.

Best for

  • Low-power voltage monitoring
  • I2C-connected sensor interfaces
  • Window threshold and alert monitoring

Avoid if

  • Applications requiring a separate precision reference input
  • Inputs outside the 0 V to VA range
  • Systems requiring more than one analog channel without external multiplexing

Check before use

  • VA supply/reference noise and bypass capacitors
  • VIN source impedance and settling
  • I2C pull-up voltage compatibility
  • VSSOP-8 pinout and address strap states
