Overview
The MAX1062CEUB+ is a low-power, 14-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This successive approximation ADC features automatic power-down, a fast 1.1µs wake-up time, and a high-speed SPI™/QSPI™/MICROWIRE™-compatible interface. It operates with a single +5V analog supply and has a separate digital supply, allowing direct interfacing with 2.7V to 5.25V digital logic. The MAX1062 is designed for applications requiring low power consumption and compact size, making it ideal for battery-powered devices, data-acquisition systems, and other circuits with stringent power and space requirements.
