TC7126A - 3-1/2 Digit Analog-to-Digital Converters

Download the TC7126A datasheet PDF. This datasheet also covers the TC7126 variant, as both devices belong to the same 3-1/2 digit analog-to-digital converters family and are provided as variant models within a single manufacturer datasheet.

General Description

The TC7126A is a 3-1/2 digit CMOS Analog-to-Digital Converter (ADC) containing all the active components necessary to construct a 0.05% resolution measurement system.

Seven-segment decoders, digit and polarity drivers, voltage reference, and clock circuit are integrated on-chip.

Key Features

  • Internal Reference with Low Temperature Drift: - TC7126: 80ppm/°C, Typical - TC7126A: 35ppm/°C, Typical.
  • Zero Reading with Zero Input.
  • Low Noise: 15VP-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 Dissipation: 500W Typ. , 900W Max.
