Overview
The MAX1062AEUB+T is a 14-bit, low-power analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This ADC features a successive approximation register (SAR) architecture and operates with a single +5V analog supply. It also includes a separate digital supply, allowing direct interfacing with 2.7V to 5.25V digital logic. The device is known for its high-speed SPI™/QSPI™/MICROWIRE™-compatible interface, automatic power-down, and fast 1.1µs wake-up time. Its excellent dynamic performance, low power consumption, and small package size make it ideal for battery-powered and data-acquisition applications.
