MAX545BESD

Digital To Analog Converters Overview

The MAX545BESD is a serial-input, voltage-output, 14-bit digital-to-analog converter (DAC) from Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and provides full 14-bit performance with ±0.5LSB INL and ±0.9LSB DNL over the -40°C to +85°C temperature range without adjustments. The device features an unbuffered voltage output, low power consumption of 1.5mW, and a 1µs settling time. It includes a 16-bit serial interface compatible with SPI/QSPI/MICROWIRE standards and a power-on reset circuit that clears the DAC output to 0V in unipolar mode upon initial power application.
