C71091 - Brand New Maxim Integrated IC Chips
-
Description
The C71091 is a 12-bit plus sign, CMOS low-power analog-to-digital converter (ADC) in the IC Chips category. It is a complete dual-slope integrating ADC requiring only eight passive components and a crystal. With features such as low input bias current, drift, and input noise, as well as auto-zero functionality, it is an attractive alternative to analog multiplexing for data acquisition applications. The C71091 also supports true differential input and reference, allowing it to measure bridge-type transducers like load cells, strain gauges, and temperature transducers.
