Rochester Electronics Data Acquisition - Digital to Analog Converters (DAC) MAX551BEPA

The MAX551BEPA is a 12-bit, current-output, multiplying digital-to-analog converter (DAC) designed for single-supply operation at +4.5V to +5.25V. It features a 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols, allowing for efficient data transfer and reduced power dissipation compared to parallel interfaces. The device supports both unipolar and bipolar output configurations, making it versatile for various applications. This DAC includes an internal power-on-reset circuit that initializes the output to 0V upon power-up, and it also has an asynchronous clear input for manual reset. The MAX551BEPA is housed in a compact 10-pin ¬µMAX package, which is advantageous for space-constrained designs. With a low supply current of 0.4¬µA and a maximum output voltage range determined by the reference input, this DAC is suitable for applications such as automatic calibration, transducer drivers, and digitally controlled filters. Engineers considering the MAX551BEPA should note its operational temperature range of -40¬8C to +85¬8C, making it suitable for industrial environments. The device's specifications, including integral nonlinearity and differential nonlinearity, ensure reliable performance in precision applications.
