The DAC8551 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 DAC8551 uses a versatile 3-wire serial interface that operates at clock rates to 30MHz and is compatible with standard SPI, QSPI, Microwire, and digital signal processor (DSP) interfaces.
The DAC8551 requires an external reference voltage to set its output range. The DAC8551 incorporates a power-on-reset circuit that ensures the DAC output powers up at 0V and remains there until a valid write takes place to the device. The DAC8551 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 ideally suited for portable, battery- operated equipment. The power consumption is 0.38mW at 2.7V, reducing to less than 1µW in power-down mode.
The DAC8551 is available in an MSOP-8 package.
For additional flexibilty, see the DAC8550, a 2's complement-input counterpart to the DAC8551.
