The MAX5290BEUD + is a low cost, 6-bit, voltage output, digital-to-analog converter (DAC) for use in data acquisition applications. It is based on a resistor string architecture and features fast settling, extreme linearity and low glitch energy. The device features a wide power supply range that makes it ideal for battery-powered, low voltage applications. It has on-chip buffering that enables it to enable high output current drive.

The MAX5290BEUD + is designed to convert digital signals with 6-bit resolution into analog voltage signals with a cascaded output. This enables the device to produce a highly accurate, fine resolution, digitally-controlled voltage output. The output voltage is adjusted through a 6-bit serial port. The device can be used in applications such as digital potentiometers, analog functions (e.g. programmable output amplifiers), and calibration controls.

The MAX5290BEUD + features an on-chip buffered output stage which enables it to drive high source or sink currents. This enables the device to drive heavier loads than conventional DACs with low supply current requirements. In addition, the device features a power-on reset logic which allows for an easy implementation of power-on reset. The device also features open-drain Logic Outputs and features a low power shutdown mode.

This device operates from a single +5V supply, accepts up to a 6-bit bus of digital data, and produces an output voltage with a 56dB dynamic range. The typical settling time is 3.2µs and the full-scale output range is 0.22V-5V. The maximum current output of the device is 300mA, which enables it to drive powered speaker systems, potentiometers, and gain controls with ease. The device also features an adjustable overrange voltage and a wide range of supply voltage operating range, which allows for its use in applications where the supply voltage is not guaranteed.

The MAX5290BEUD + is designed to be used in data acquisition applications that require accurate voltage output. It features fast settling, high linearity, and low glitch energy. It is ideal for applications where a wide range of supply voltages can be used, and its on-chip buffering gives it the ability to drive heavy loads. Further, it is easy to implement into applications due to its wide range of features and operating ranges.
