Overview
The MAX1262BEEI+ is a low-power, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX1262/MAX1264 family, which features successive-approximation ADCs with automatic power-down, fast wake-up, and an on-chip clock. The MAX1262BEEI+ operates with a single +5V analog supply and includes a VLOGIC pin that allows it to interface directly with a +2.7V to +5.5V digital supply. This ADC is designed for applications requiring high dynamic performance, low power consumption, and compact packaging.
