Rochester Electronics Data Acquisition - Digital to Analog Converters (DAC) MAX5121AEEE

The MAX5121AEEE is a low-power, 12-bit digital-to-analog converter (DAC) designed for voltage output applications. It operates on a +3V supply and features an internal precision bandgap reference of +1.25V, providing a full-scale output of +2.0475V. The device is capable of drawing only 500¬µA of supply current, which reduces to 3¬µA in power-down mode, making it suitable for energy-sensitive applications. This DAC supports a serial interface compatible with SPI,Ñ¢, QSPI,Ñ¢, and MICROWIRE,Ñ¢, allowing for easy integration and cascading of multiple devices. It includes a double-buffered input structure, enabling independent or simultaneous updates of the DAC register. The MAX5121AEEE is housed in a 16-pin QSOP package and is specified for an extended industrial temperature range of -40¬8C to +85¬8C. Key features include a power-up reset function that allows for a user-selectable initial output state, minimizing output voltage glitches during power-up. The device is suitable for various applications, including industrial process controls, automatic test equipment, and microprocessor-controlled systems.
