Overview
The MAX1274BETC+ is a high-performance, low-power, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device operates at a sampling rate of up to 1.8 million samples per second (Msps) and is designed for applications requiring high-speed conversion, low power consumption, and excellent signal integrity. The MAX1274BETC+ features true-differential inputs, which provide better noise immunity and distortion improvements compared to single-ended inputs. It is suitable for a wide range of applications, including industrial process control, motor control, and communications.
