General Description

The MAX530 is a low-power, 12-bit, voltage-output digital-to-analog converter (DAC) that uses single +5V or dual ±5V supplies. This device has an on-chip voltage reference plus an output buffer amplifier. Operating current is only 250μA from a single +5V supply, making it ideal for portable and battery-powered applications. In addition, the SSOP (Shrink-Small-Outline-Package) measures only 0.1 square inches, using less board area than an 8-pin DIP. 12-bit resolution is achieved through laser trimming of the DAC, op amp, and reference. No further adjustments are necessary.
