General Description

The MAX503 is a low-power, 10-bit, voltage-output digital-to-analog converter (DAC) that uses single 5V or dual ±5V supplies. This device has an internal 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 shrink smalloutline package (SSOP) measures only 0.1 square inches, using less board area than an 8-pin DIP. 10-bit resolution is achieved through laser trimming of the DAC, op amp, and reference. No further adjustments are necessary.
