Overview
The MAX11102AUB+ is a high-performance, low-power, serial 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This compact ADC is housed in a 10-pin µMAX package and features a successive approximation architecture. It includes a high dynamic range sample-and-hold circuit and a high-speed serial interface, making it ideal for applications requiring low power consumption and minimal space.
The device accepts a full-scale input from 0V to the power supply or to the reference voltage and features dual, single-ended analog inputs connected to the ADC core using a 2:1 multiplexer. It also includes a separate supply input for the data interface and a dedicated input for the reference voltage. The MAX11102AUB+ offers full power-down mode and fast wake-up for optimal power management, along with a high-speed 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE devices without external logic.
