Intersil ICL7109
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. The RUN/HOLD input and STATUS output allow monitoring and control of conversion timing.| Part No. | ICL7109 |
