Overview
The MAX1079CTC+ is a low-power, high-speed, 10-bit analog-to-digital converter (ADC) produced by Analog Devices Inc., which acquired Maxim Integrated. This device operates at a sampling rate of up to 1.5 million samples per second (Msps) and features true-differential inputs, providing better noise immunity, distortion improvements, and a wider dynamic range compared to single-ended inputs. It is designed for applications requiring high-speed conversion, low power consumption, and excellent AC and DC performance.
