Product Overview

DC845A QuickEval™ demonstration board for the evaluation of LTC2448 ADCs with selectable speed/resolution. It is a 24bit high speed 8/16 channel no latency delta sigma ADC. They use a proprietary delta sigma architecture enabling variable speed/resolution. Through a simple 4 wire serial interface, ten speed/resolution combinations can be selected with no latency between conversion results or shift in DC accuracy. While operating in the 1X speed mode the first conversion following a new speed, resolution, or channel selection is valid. Since there is no settling time between conversions, all 8 differential channels can be scanned at a rate of 500Hz. At the conclusion of each conversion, the converter is internally reset eliminating any memory effects between successive conversions and assuring stability of the high order delta sigma modulator. DC845A can also evaluate LTC2448 ADC while using the DC590 USB Serial Controller board and supplied software to measure performance.
  • Up to 8 differential or 16 single ended input channels
  • Up to 8kHz output rate
  • Up to 4kHz multiplexing rate
  • Selectable speed/resolution
  • Guaranteed modulator stability and lock up immunity for any input and reference conditions
  • Differential input and differential reference with GND to Vcc common mode range
  • No latency mode, each conversion is accurate even after a new channel is selected
