Overview
The MAX1072ETC+ is a high-performance, low-power, 10-bit analog-to-digital converter (ADC) designed by Analog Devices Inc., which has integrated Maxim Integrated's product portfolio. This device operates at a sampling rate of up to 1.8 million samples per second (Msps) and is suitable for various high-speed data acquisition applications. The MAX1072ETC+ features true-differential inputs, which provide better noise immunity, distortion improvements, and a wider dynamic range compared to single-ended inputs. It operates from a single supply voltage of +4.75V to +5.25V and requires an external reference voltage. The device is available in a compact 12-pin TQFN package and supports an extended temperature range of -40°C to +85°C.
