Overview
The MAX1071CTC+ is a high-speed, low-power, 10-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device operates at up to 1.5 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 MAX1071CTC+ is designed for applications requiring high-speed conversion with low power consumption and is available in a compact 12-pin TQFN package.
