Description
The ICL7109 is a high performance, CMOS, low power integrating A/D converter designed to easily interface with microprocessors.
The output data (12 bits, polarity and over-range)may be directly accessed under control of two byte enable inputs and a chip select input for a single parallel bus interface. A UART handshake mode is provided to allow the lCL7109 to work with industry-standard UARTs in providing serial data transmission. The RUN/HOLD input and STATUS output allow monitoring and control of conversion timing.
The lCL7109 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/℃, 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.

I recently purchased the ICL7109CPL integrated circuit from Utsource and I am very pleased with the results. The circuit was delivered quickly and in excellent condition. I tested it and found that it performed exactly as expected. The circuit was easy to set up and use, and the instructions were clear and concise. I am very satisfied with the qu of the product and the service I received from Utso
