Product Overview

The AD7716BPZ is a 22-bit signal processing block Data Acquisition System capable of processing four channels with bandwidths of up to 584Hz. The device consists of four separate A/D converter channels that are implemented using sigma-delta technology. Sigma-delta ADCs include on-chip digital filtering and thus the system filtering requirements are eased. This allows a data acquisition system with up to 32-channel to be set up in a simple fashion. The output word from the device contains 32-bit of data. 1-bit is determined by the state of the DIN1 input and may be used, for example, in an ECG system with an external pace-maker detects circuit to indicate that the output word is invalid because of the presence of a pacemaker pulse. 2-bit contains the channel address and 3-bit are the device address. Thus, each channel in a 32-channel system would have a discrete 5-bit address. The device also has a CASCOUT pin and a CASCIN pin that allow simple networking of multiple devices.
  • On-chip low-pass digital filter
  • Linear phase response
  • 5-Line serial I/O
  • Twos complement coding
  • Easy interface to DSPs and microcomputers
  • Software control of filter cut-OFF
