Overview
The MAX1062AEUB, produced by Analog Devices Inc./Maxim Integrated, is a low-power, 14-bit analog-to-digital converter (ADC) designed for applications requiring high precision, low power consumption, and compact packaging. 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 on 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 ideal for battery-powered devices, data-acquisition systems, and other applications with stringent power and space requirements.
