Part Description

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 30 MHz 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 0 V 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 200 nA at 5 V. The low-power consumption of this device in normal operation makes it ideally suited for portable, batteryoperated equipment. The power consumption is 0.38 mW at 2.7 V, reducing to less than 1 μW in power‑down mode. For additional flexibilty, see the DAC8550 (SLAS476), a 2's complement-input counterpart to the DAC8551.
