Overview
The MAX1110CPP, produced by Analog Devices Inc./Maxim Integrated, is a low-power, multichannel, serial 8-bit analog-to-digital converter (ADC). This device is designed for applications requiring high accuracy and low power consumption. It operates from a single supply voltage ranging from 2.7V to 5.5V and is particularly suited for use in portable and battery-powered systems due to its low power consumption of 85µA at a sampling rate of 50ksps.
