Product Overview

The ADS8556EVM is an evaluation board for the ADS8556 high precision analog to digital converter. The ADS8556 is a high speed, low power, six channel 16bit A/D converter that operates from independent ±HVDD (±5V to ±15V), 5V AVdd and DVdd supplies. The digital output is delivered through a built in buffer circuit that can be powered from DVdd or separate 2.7V to 5.25V (BVdd) sources. This allows for flexibility when designing within mixed voltage environments. The six sample and hold circuits are divided into three pairs (A, B and C). Each pair of channels has a hold signal (CONVST_A, CONVST_B, and CONVST_C) which, when strobed together, allows simultaneous sampling on all six analog inputs. The part accepts bipolar analog input voltages in the range of up to ±12V. Conversion time for the ADS8556 is 1.19µs maximum when operated in hardware mode. Throughput is up to 670kSPS when operated in the parallel interface mode or 470kSPS when operated in serial interface mode.
  • Fully featured evaluation board for the ADS8556 parallel/serial ADC
  • On board or off board references using on board jumpers
  • Compatible with the 5K to 6k interface board, DSK starter kits and HPA-MCU interface
  • Operate at a sampling rates up to 730kSPS
  • Supports serial or high speed parallel interface modes
  • Analog inputs can be configured for direct application to the ADC or applied through buffer circuits
  • Supports serial or high speed parallel interface modes
