Overview
The MAX1279ACTC+ is a high-performance, low-power, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. (now part of Maxim Integrated). This device is designed for applications requiring high-speed conversion, low power consumption, and excellent AC and DC performance. The MAX1279 operates from a single supply voltage of +2.7V to +3.6V and features a true-differential input, which provides better noise immunity, distortion improvements, and a wider dynamic range compared to single-ended inputs.
