Overview
The MAX1274AETC+T 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 features true-differential analog inputs, which provide better noise immunity and distortion improvements compared to single-ended inputs. The MAX1274AETC+T is designed for a wide range of applications requiring high-speed data acquisition with low power consumption.
