Overview
The MAX1277AETC, produced by Analog Devices Inc./Maxim Integrated, is a high-performance, low-power, 12-bit analog-to-digital converter (ADC). This device operates at speeds of up to 1.5 million samples per second (Msps) and features a single-supply voltage range of +2.7V to +3.6V. It is designed with true-differential inputs, which provide better noise immunity, distortion improvements, and a wider dynamic range compared to single-ended inputs. The MAX1277AETC includes an internal reference and supports standard SPI™/QSPI™/MICROWIRE™ interfaces, making it compatible with various digital signal processors (DSPs) and microcontrollers.
