Product Summary
The UPD7001C is a high performance, low power 8-bit CMOS A/D converter which consists of a 4-channel analog multiplexer and a digital interface circuit for serial fata I/O. It uses successive approximation as a conversion technique. An A/D conversion system can be easily designed withe the UPD7001C including all circuits for A/D conversion. The UPD7001C can be directly connected to 8-bit or 4-bit microprocessors.
