TC7109 - 12-BIT UP-COMPATIBLE ANALOG-TO-DIGITAL CONVERTERS

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

  • s s s s s s s s s s Zero-Integrator Cycle for Fast Recovery From Input Overloads Eliminates Cross -Talk in Multiplexed Systems 12-Bit Plus Sign Integrating A/D Converter With Overrange Indication Sign Magnitude Coding Format True Differential Signal Input and Differential Reference Input Low Noise 15 µVP-P Typ Input Current 1 pA Typ No Zero Adjustment Needed TTL-Compatible, Byte-Organized Tri-State Outputs UART Handshake Mode for Simple Serial Data Transmission.
