Analog to Digital Converters (ADC)

10-bit ADC16-channel ADCSAR ADC1 MSPSSPI ADCexternal referenceRHB VQFN

ADS7957SRHBR is a 16-channel, 10-bit SAR ADC for multiplexed single-ended measurement systems requiring up to 1 MSPS throughput.

Best for

  • 16-channel single-ended measurement systems
  • Industrial data acquisition
  • Systems using external precision references

Avoid if

  • A higher-resolution ADC is required
  • The source impedance cannot meet settling requirements without buffering
  • More than one GPIO is required in the VQFN package

Check before use

  • Verify the selected 0 to VREF or 0 to 2×VREF input range.
  • Keep analog inputs within specified absolute limits.
  • Use a clean external reference with a 10 µF ceramic capacitor between REFP and REFM.
  • Check channel-to-channel settling when multiplexing large signal steps.
