TC7109CKW Data & Signal Conversion by Microchip Technology

12-Bit Dual Slope Analog-to-Digital Converter


The TC7109 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. The improved Voh source current TC7109 has features that make it an attractive per-channel alternative to analog multiplexing for many data acquisition applications. These features include typical input bias current of 1pA, drift of less than 1 µV/°C, input noise typically 15 µVp-p, and auto-zero. True differential input and reference allow measurement of bridge-type transducers such as load cells, strain gauges, and temperature transducers. In the handshake mode, the TC7109 will operate with industry-standard UARTs in controlling serial data transmission - ideal for remote data logging.
