10.2.3.1 Design Requirements

Portable and battery-powered applications require ultralow-power consumption and do not need very high throughput from the ADC.

Design a single-supply, data acquisition circuit optimized for using the ADS8860 to achieve

  • ENOB > 14.5 bits and
  • Ultralow-power consumption of < 1 mW at throughput of 10 kSPS
