The ICL7109 is a high performance, CMOS, low powerintegraTIng A/D converter designed to easily interface withmicroprocessors.The output data (12 bits, polarity and over-range) may bedirectly accessed under control of two byte enable inputs and achip select input for a single parallel bus interface. A UARThandshake mode is provided to allow the ICL7109 to work withindustry-standard UARTs in providing serial data transmission.The RUN/HOLD input and STATUS output allow monitoringand control of conversion TIming.The ICL7109 provides the user with the high accuracy, lownoise, low drift versaTIlity and economy of the dual-slopeintegraTIng A/D converter. Features like true differential inputand reference, drift of less than 1μV/oC, maximum input biascurrent of 10pA, and typical power consumption of 20mWmake the ICL7109 an attractive per-channel alternative toanalog multiplexing for many data acquisition applications.
