Overview
The MAX1113CEE+T is a low-power, 8-bit, multi-channel analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX1112/MAX1113 family and is designed for applications requiring high accuracy and low power consumption. It operates from a single 4.5V to 5.5V supply and features an internal track/hold, voltage reference, clock, and serial interface. The MAX1113 is particularly suited for systems that need to convert multiple analog signals into digital data efficiently.
