Overview
The MAX1224CTC+ is a high-performance, low-power, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device operates at a sampling rate of up to 1.5 million samples per second (Msps) and is designed for applications requiring high speed and low power consumption. The MAX1224CTC+ features true-differential inputs, which provide better noise immunity, distortion improvements, and a wider dynamic range compared to single-ended inputs.
