Overview
The MAX1278CTC+ is a high-performance, low-power, 12-bit 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 enhances noise immunity, reduces distortion, and increases the dynamic range compared to single-ended inputs. The MAX1278CTC+ is designed for applications requiring high-speed conversion, low power consumption, and excellent AC and DC performance.
