Overview
The MAX1274ACTC+T is a 12-bit, low-power, high-speed analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device operates at up to 1.8 million samples per second (Msps) and features a true-differential input, which provides better noise immunity, distortion improvements, and a wider dynamic range compared to single-ended inputs. The MAX1274ACTC+T is packaged in a 12-pin TQFN (4x4) package and is suitable for various applications requiring high-speed and low-power conversion.
