The ICL7129A is a high precision monolithic 4-1/2 digit AID converter that directly drives a multiplexed liquid crystal display. Using a novel “successive integration” technique, the ICL7129A 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 DVIWIDPMs is a reference. The over range and under-range outputs and the 10:1 range changing input facilitate the design of autoranging systems. The ICL7129A detects and flags a LOW BATTERY condition and also checks for continuity, giving a visual indication and a logic level output which can be used to generate an audible signal.
