Overview
The MAX1075CTC+T, produced by Analog Devices Inc./Maxim Integrated, is a high-performance, low-power, 10-bit analog-to-digital converter (ADC). This device operates at a sampling rate of up to 1.8 million samples per second (Msps) and is designed for applications requiring high speed, low power consumption, and excellent signal integrity.
The MAX1075 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.
