ES5107 is a low power monolithic CMOS 3 1/2 digit LCD display A/D converter from Cyrustek.
The CYRUSTEK ES5107 is a low power monolithic CMOS 3 1/2 digit LCD display A/D converter. The single chip provides all necessary active devices, including the internal clock, voltage reference, seven-segment decoders, and back plane driver. It features an improved internal zener reference voltage circuit with a small temperature coefficient of 60 ppm/°C typically.
The device is designed for high accuracy applications such as digital panel meters, multimeters, thermometers, and pH meters. Key characteristics include low input leakage current (1pA typical), differential input suitable for bridge transducers, and dual slope conversion technique for high rejection of line frequency noise.
