Product Summary
The ICL7109IJL is a Microprocessor-Compatible A/D Converter. It is a high performance, CMOS, low power integrating A/D converter designed to easily interface with microprocessors. The ICL7109IJL provides the user with the high accuracy, low noise, low drift versatility and economy of the dual-slope integrating A/D converter. Features like true differential input and reference, drift of less than 1μV/oC, maximum input bias current of 10pA, and typical power consumption of 20mW make the ICL7109 an attractive per-channel alternative to analog multiplexing for many data acquisition applications.
