ICL7107CQH-D

ADCs/DACs - Special Purpose Overview

The ICL7107CQH+D is a 3.5-digit analog-to-digital converter (ADC) designed for direct LED display drive, manufactured by Analog Devices Inc./Maxim Integrated. It integrates seven-segment decoders, display drivers, a reference, and a clock within a 44-pin PLCC package. The device operates on a single 5V supply with typical power dissipation under 10mW. Key electrical characteristics include a typical input bias current of 1pA, peak-to-peak noise less than 15µV, and an autozero capability below 10µV. It supports true differential inputs and references, making it suitable for precision measurements of bridge-type transducers.
