Features and Overview

  • Samples two inputs simultaneously
  • 8-bit resolution
  • 2’s complement or unsigned result
  • Sample rates from 122 to greater than 7600 sps
  • Multiple input ranges including Vss to Vdd
  • Integrating Converter provides good normal mode rejection
  • Sample rate may be changed dynamically to sync to input signal
  • Internal or external clock

The DualADC8 is a dual input integrating 8-bit Analog to digital converter. It can be configured to remove unwanted high frequencies by optimizing the integrate time. Input voltages within 40 mV or less, of the supply rails may be measured by configuring the proper reference voltage and analog ground. The output is configurable 2’s complement or unsigned chars based on an input voltage between –Vref and Vref centered at AGND.
