3 Description
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.
The DAC8560 is available in an 8-pin VSSOP
package.
