HI7131 - LCD/LED Display-Type A/D Converters

General Description

The Intersil HI7131 and HI7133 are 31/2 digit, A/D converters that have been optimized for superior DC Common Mode Rejection (CMRR) when used with a split ±5V supply or a single 9V battery.

Key Features

  • in all systems, but gives the designer an advantage when measuring load cells, strain gauges and other bridge-type transducers. The HI7131 and HI7133 are supplied in a 40 lead plastic DIP and a 44 lead metric plastic quad flatpack package. Features.
  • 120dB CMRR Equal to ±0.01 Count/V of Common Mode Voltage Error.
  • Fast Recovery from Input Overrange Results “Correct First-Reading” After Overload.
  • Guaranteed 0000 Reading for 0V Input.
  • True Polarity at Zero for Pr.
