General Description

This integrated circuit contains a plete signal conditioning system to interface low-level variable impedance transducers to a digital system.

A pair of matched, temperature-pensated current sources are provided for balanced transducer excitation followed by a precision, high-gain parator.

The output of this parator can be delayed by a user-selectable duration, after which a second parator will switch plementary outputs separately activated for diagnostic operation and has an optional latch with external reset capability.

Key Features

  • Dual Matched Current Sources.
  • High-gain Differential Sensing Circuit.
  • Wide Common-mode Input Capability.
  • Complementary Digital Open-collector Outputs.
  • Externally Programmable Time Delay.
  • Optional Output Latch with Reset.
  • Built-in Diagnostic Activation.
  • Wide Supply Voltage Range.
  • High Current Heater Power Source Driver UC3704.
