5.5 V 12-位 模数转换器 表面贴装 - PLCC-44
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.
The improved VOH source current TC7109A 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 1µV/°C, input noise typically 15µVP-P, and auto-zero. True differential input and reference allow measurement of bridge-type transducers such as load cells, strain gauges, and temperature transducers.
