ADC122S021 - 12-Bit A/D Converter

General Description

The ADC122S021 is a low-power, two-channel CMOS 12-bit analog-to-digital converter with a highspeed serial interface.

Unlike the conventional practice of specifying performance at a single sample rate only, the ADC122S021 is fully specified over a sample rate range of 50 ksps to 200 ksps.

Key Features

  • 1.
  • 2 Specified over a Range of Sample Rates.
  • Two Input Channels.
  • Variable Power Management.
  • Single Power Supply with 2.7V - 5.25V Range.
