Overview
The MAX1276CTC+T, produced by Analog Devices Inc./Maxim Integrated, is a high-performance, low-power, 12-bit analog-to-digital converter (ADC) designed for a variety of applications requiring high speed and precision. 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 MAX1276CTC+T includes an internal 4.096V reference and supports a standard SPI/QSPI/MICROWIRE interface, making it compatible with standard digital signal processor (DSP) synchronous serial interfaces.
