Product Overview

DC846A QuickEval™ demonstration board for the evaluation of LTC2447 ADC with selectable multiple reference inputs. The LTC2447 is a 4-/8 channel, high speed, 24bit delta sigma ADC with ten selectable speed/resolution modes. The accuracy and power dissipation are independent of the speed selected. The LTC2447 also has four reference inputs dedicated to the four differential input channels and corresponding pairs of single ended input channels. This allows the inputs to have different reference sources, facilitating independent ratiometric measurements on each channel. The LTC2447 performs auto zeroing of the ADC by chopping the inputs through the multiplexer outputs. This allows an external dual buffer amplifier to isolate the signal inputs from the sampling current of the ADC inputs. DC846A can also evaluate LTC2447 while using the DC590 USB serial controller board and supplied software to measure performance.
  • Five selectable differential reference inputs
  • Four differential/eight single ended inputs
  • 4 way MUX for multiple ratiometric measurements
  • Up to 8kHz output rate
  • Up to 4kHz multiplexing rate
  • 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
  • Includes MUXOUT/ADCIN for external buffering or gain
