The DAC8550 is a small, low-power, voltage output, 16-bit digital-to-analog converter (DAC). It is monotonic, provides good linearity, and minimizes undesired code-to-code transient voltages. The DAC8550 uses a versaTIle, 3-wire serial interface that operates at clock rates of up to 30MHz and is compaTIble with standard SPI™, QSPI™, Microwire™, and digital signal processor (DSP) interfaces.
The DAC8550 requires an external reference voltage to set its output range. The DAC8550 incorporates a power-on reset circuit that ensures that the DAC output powers up at midscale and remains there unTIl a valid write takes place to the device. The DAC8550 contains a power-down feature, accessed over the serial interface, that reduces the current consumpTIon of the device to 200nA at 5V.
