Overview
The MAX1062ACUB+ is a 14-bit, low-power analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device features a successive approximation ADC architecture and is designed for high-performance and low-power applications. It operates with a single +5V analog supply and has a separate digital supply, allowing it to interface directly with digital logic ranging from 2.7V to 5.25V. The MAX1062 is known for its fast wake-up time of 1.1µs and high-speed SPI™/QSPI™/MICROWIRE™-compatible interface. Its small package size (10-pin µMAX®) and excellent dynamic performance make it ideal for battery-powered and data-acquisition applications.
