ADS1261IRHBR

Analog to Digital Converters (ADC)

24-bit ADCdelta-sigmaprecision ADCPGARTDSPIVQFN-32

ADS1261IRHBR is a precision 24-bit delta-sigma ADC for low-level sensor measurement, offering multiplexed inputs, gain to 128 V/V, excitation current sources, and digital filtering up to 40 kSPS.

Best for

  • Precision resistive sensor measurement
  • Multiplexed low-level voltage measurement
  • RTD and bridge-sensor front ends

Avoid if

  • A simple low-pin-count ADC is required
  • The application cannot accommodate shared analog-input alternate functions

Check before use

  • Validate absolute and differential PGA input range
  • Add the required 4.7 nF C0G capacitor between CAPP and CAPN
  • Add the required 10 µF capacitor from REFOUT to AVSS when using the internal reference
