ADS7947SRTER

Analog to Digital Converters (ADC)

12-bit ADC2-channel ADCSAR ADC2 MSPSPseudo-differentialSPIWQFN

ADS7947SRTER is a 12-bit, two-channel SAR ADC for low-power data-acquisition designs requiring pseudo-differential inputs and SPI-compatible output at up to 2 MSPS in a compact WQFN package.

Best for

  • Dual-channel data acquisition
  • Low-power sensor interfaces
  • SPI-connected embedded measurement systems

Avoid if

  • A true differential input ADC is required
  • An integrated voltage reference is required
  • More than two simultaneously sampled channels are needed

Check before use

  • Verify AINxP minus AINxN remains within the 0 V to VREF full-scale range.
  • Keep AINxN signal swing within the specified ±0.2 V range.
  • Place the required 1 µF ceramic capacitor close to REF and REFGND.
  • Validate the acquisition-time settling requirement for the source impedance and input filter.
