Overview
The MAX1301, produced by Analog Devices Inc./Maxim Integrated, is a multirange, low-power, 16-bit successive-approximation analog-to-digital converter (ADC). This device operates from a single +5V supply and achieves throughput rates up to 115ksps. It features a separate digital supply, allowing digital interfacing with systems operating between 2.7V and 5.25V through an SPI-/QSPI™-/MICROWIRE®-compatible serial interface. The MAX1301 is designed to provide high flexibility and low power consumption, making it suitable for a variety of applications requiring precise analog-to-digital conversion.
