Overview
The MAX1275ACTC+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 inputs, which provide better noise immunity, distortion improvements, and a wider dynamic range compared to single-ended inputs. The MAX1275 is designed for applications requiring high-speed conversion, low power consumption, and excellent AC and DC performance.
