Product Introduction

Overview

The MAX1238EEE/V+ is a low-power, 12-channel, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device operates from a single supply voltage of 4.5V to 5.5V and features an I²C-compatible 2-wire serial interface. It is designed for applications requiring high accuracy and low power consumption, making it suitable for a variety of industrial, medical, and portable devices. The ADC includes internal track/hold (T/H), voltage reference, and clock, and it supports both unipolar and bipolar, as well as single-ended and differential analog input configurations.
