Overview
The MAX1110, part of the MAX1110/MAX1111 series, is a low-power, 8-bit, multichannel analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is designed for high efficiency and versatility, making it suitable for a wide range of applications. The MAX1110 operates from a single supply voltage ranging from 2.7V to 5.5V and features an internal track/hold, voltage reference, clock, and serial interface. It is particularly noted for its low power consumption, with a current draw of only 85µA while sampling at rates up to 50ksps.
