TC500

The TC500 is a precision analog front end dual slope A/D converter having a maximum resolution of 16 bits plus sign. The device contains the integrator, zero crossing comparator and processor interface logic, and requires both positive and negative power supplies. The TC500 offers high resolution (up to 16 bits), superior 50Hz/60Hz noise rejection, low power operation, minimum I/O connections, and low input bias currents.

Features
  • Precision (up to 16 Bits) A/D Converter Front End
  • 3-Pin Control Interface to Microprocessor
  • Flexible: Ability to Trade-Off Conversion Speed for Resolution
  • Automatic Input Voltage Polarity Detection
  • Low Power Dissipation: 10mW
  • Wide Analog Input Range: ±4.2V
  • Directly Accepts Bipolar and Differential Input Signals
