ADS1191IRSMR

Analog Front End (AFE)

16-bit AFEbiopotentialECGsingle-channeldelta-sigma ADCVQFN-32SPIlead-off detection

ADS1191IRSMR is a low-power, single-channel 16-bit biopotential AFE for ECG-class acquisition, integrating a PGA, delta-sigma ADC, reference, oscillator, lead-off detection, and SPI interface.

Best for

  • Single-channel ECG acquisition
  • Portable biopotential instruments
  • Heart-rate and fitness monitoring

Avoid if

  • More than one simultaneous ADC channel is required
  • The design cannot support external patient-protection and RLD-loop circuitry

Check before use

  • Verify gain and reference selection against expected electrode signal and offset
  • Use the required VCAP, VREF, supply-decoupling, and PGA output capacitors
  • Validate lead-off and RLD behavior in the complete electrode system
