Overview
The MAX1071CTC+T 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 is designed for applications requiring high-speed conversion with low power consumption. The MAX1071 features true-differential inputs, which offer better noise immunity, distortion improvements, and a wider dynamic range compared to single-ended inputs. It operates from a single supply voltage of +2.7V to +3.6V and requires an external reference voltage.
