MAX7129CPL+ - Maxim Integrated Function Overview

The MAX7129CPL+ from Maxim Integrated Products is a low-noise, 4 1/2 digit, single-chip ADC with multiplexed LCD driver in 40 pin DIP package. It is a high precision monolithic 4-1/2 digit ADC that directly drives a multiplexed liquid crystal display. Using a novel "successive integration" technique, the MAX7129 has a ±20,000 count resolution on both 2.00000V and 200.00mV ranges. It features high impedance differential inputs, excellent differential linearity, true ratiometric operation and auto polarity. The only external active component required to make precision DVM/DPMs is a reference. The overrange and underrange outputs and the 10:1 range changing input facilitate design of autoranging systems. The MAX7129 detects and flags LOW BATTERY condition and also checks for continuity, giving a visual indication and logic level output which can be used to generate an audible signal. It is used in precision digital voltmeter, mustimeter and panel meter applications.
