TC7136 - Low Power 3-1/2 Digit Analog-to-Digital Converter

General Description

The TC7136 and TC7136A are low power, 3-1/2 digit with liquid crystal display (LCD) drivers and analog-todigital converters.

These devices incorporate an "integrator output zero" phase, which enables over range recovery.

Key Features

  • Fast Over Range Recovery, Ensured First Reading Accuracy.
  • Low Temperature Drift Internal Reference - TC7136: 70ppm/°C (Typ. ) - TC7136A: 35ppm/°C (Typ. ).
  • Zero Reading with Zero Input.
  • Low Noise: 15μVP-P.
  • High Resolution: 0.05%.
  • Low Input Leakage Current: 1pA (Typ. )/10pA (Max. ).
  • Precision Null Detectors with True Polarity at Zero.
  • High-Impedance Differential Input.
  • Convenient 9V Battery Operation with Low Power Dissi.
