TC500 - Precision Analog Front Ends

Description

TheTC500/A/510/514 family are precision analog front ends that implement dual slope A/D converters having a maximum resolution of 17 bits plus sign.

As a minimum, each device contains the integrator, zero crossing comparator and processor interface logic.

Features

  • Precision (up to 17 bits) A/D Converter “Front End”.
  • 3-Pin Control Interface to Microprocessor.
  • Flexible: User Can Trade-off Conversion Speed for Resolution.
  • Single-Supply Operation (TC510/TC514).
  • 4 Input, Differential Analog MUX (TC514).
  • Automatic Input Voltage Polarity Detection.
  • Low Power Dissipation: - (TC500/TC500A): 10 mW - (TC510/TC514): 18 mW.
  • Wide Analog Input Range: - ±4.2V (TC500A/TC510).
  • Directly Accep.
