Overview
The MAX1302BEUG+ is a multirange, low-power, 16-bit successive-approximation analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This ADC operates from a single +5V supply and achieves throughput rates up to 115ksps. It features a SPI-/QSPI-/MICROWIRE®-compatible serial interface, allowing digital interfacing with systems using supply voltages from 2.7V to 5.25V. The device is designed for low power consumption, with partial power-down mode reducing the supply current to 1.3mA (typ) and full power-down mode reducing it to 1µA (typ).
