Product Summary

The MAX7129CPL is a high precision monolithic 4-1/2 digital A/D converter that directly drives a multipexed liquid crystal display. Using a novel “successive integration” technique, the MAX7129CPL has a ±20000 count resolution on both 200000V and 200.00mV ranges. The MAX7129CPL can be used for a wide range of precision digital voltmeter, multimeter and panelmeter applications.
