Overview
The MAX1285BCSA+T, produced by Analog Devices Inc./Maxim Integrated, is a 12-bit analog-to-digital converter (ADC) designed for high-speed, low-power applications. This device combines a high-bandwidth track/hold (T/H) circuit, a successive-approximation register (SAR) for analog-to-digital conversion, and a 3-wire serial interface compatible with SPI™/QSPI™/MICROWIRE™ devices. The MAX1285 operates from a single supply voltage of +2.7V to +3.6V, making it suitable for power-sensitive and space-constrained designs.
