The MAX5154ACE is a highly integrated device that allows easy generation of high-precision analog signals from microprocessors or digital logic products. This device combines a 10-bit resolution, microprocessor- or logic-compatible digital-to-analog converter (DAC) with an onboard reference current regulator and an internal high-stability buried zero-scale (ZS) resistor network. As a result, the MAX5154ACE eliminates the tedious external component-matching process normally associated with applications requiring a precisely matched voltage across the output. Its reference current regulation circuit provides the servo action needed to eliminate any drift in the output voltage.

The MAX5154ACE provides both a differential output voltage and a single-ended output voltage at its pins. The voltages are determined by the digital input word, the zero-scale resistance network, and the reference current. The 10-bit resolution provides an accuracy of ± 0.2% of the full-scale voltage span. The device is fully specified for operation with a single 5VDC supply, which makes it ideal for battery-powered applications.

With its very low power consumption and on-chip precision reference, the MAX5154ACE is an ideal choice for data acquisition or other applications requiring a high-precision analog output. The device also provides excellent power-supply rejection and low output offset voltage and no internal offset trimming is required. This makes the MAX5154ACE a perfect solution for systems with varying input voltage or with unstable power supplies. Combined with its 0.6 μs settling time and its excellent speed performance, the MAX5154ACE is a premier choice for many data acquisition applications.
