TC7109A - Analog-to-Digital Converters

Download the TC7109A datasheet PDF. This datasheet also covers the TC7109 variant, as both devices belong to the same analog-to-digital converters family and are provided as variant models within a single manufacturer datasheet.

General Description

The TC7109A is a 12-bit plus sign, CMOS low power Analog-to-Digital Converter (ADC).

Only eight passive components and a crystal are required to form a complete dual slope integrating ADC.

Key Features

  • Zero Integrator Cycle for Fast Recovery from Input Overloads.
  • Eliminates Cross-Talk in Multiplexed Systems.
  • 12-Bit Plus Sign Integrating A/D Converter with Over Range Indication.
  • Sign Magnitude Coding Format.
  • True Differential Signal Input and Differential Reference Input.
  • Low Noise: 15VP-P Typ.
  • Input Current: 1pA Typ.
  • No Zero Adjustment needed.
  • TTL Compatible, Byte Organized Tri-State Outputs.
  • UART Ha.
