The DAC8550IDGKT is a small low-power voltage output 16-bit Digital-to-analog Converter (DAC) 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. The low-power consumption of this device in normal operation makes it ideal for portable, battery-operated equipment. Power consumption is 0.38mW at 2.7V, reducing to less than 1µW in power-down mode.
