MAX545AESD+T

Digital To Analog Converters Overview

The MAX545AESD+T 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 temperature without adjustments. The device features an unbuffered output, resulting in low supply current of 0.3mA and offset error of 0.6mV. It includes a 10MHz, 3-wire serial interface compatible with SPI/QSPI/MICROWIRE standards. The component is housed in a 14-pin SO package and supports an operating temperature range of -40°C to +85°C.
