Overview
The MAX11101EUB+ is a low-power, 14-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This ADC features a successive approximation architecture and is designed for applications requiring high precision and low power consumption. 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 device is notable for its fast wake-up time of 1.1µs and a high-speed SPI/QSPI™/MICROWIRE®-compatible interface. Its small package size, available in 10-pin µMAX and 12-bump WLP, makes it ideal for battery-powered and data-acquisition systems, as well as other circuits with stringent power and space requirements.
