The DAC8560 is a low-power, voltage output, 16-bit digital-to-analog converter (DAC).
The DAC8560 includes a 2.5-V, 2-ppm/°C internal reference (enabled by default), giving a full-scale output voltage range of 0 V to 2.5 V.
The internal reference has an initial accuracy of 0.02% and can source up to 20 mA at the VREF pin.
The device is monotonic, provides very good linearity, and minimizes undesired code-tocode transient voltages (glitch).
The DAC8560 uses a versatile 3-wire serial interface that operates at clock rates up to 30 MHz.
It is compatible with standard SPI, QSPI, Microwire, and digital-signal-processor (DSP) interfaces.
The DAC8560 incorporates a power-on-reset (POR) circuit that ensures the DAC output powers up at zero scale and remains there until a valid code is written to the device.
The DAC8560 contains a power-down feature, accessed over the serial interface, that reduces the current consumption of the device to 1.2 μA at 5 V.
The low-power consumption, internal reference, and small footprint make this device ideal for portable, battery-operated equipment.
The power consumption is 2.6 mW at 5 V, reducing to 6 μW in power-down mode.
