3 Description
The DAC756x-Q1, DAC816x-Q1, and DAC856x-Q1
(DACxx6x-Q1) devices are low-power, voltage-output,
dual-channel, 12-, 14-, and 16-bit digital-to-analog
converters (DACs), respectively. These devices
include a 2.5-V, 4-ppm/°C internal reference, giving a
full-scale output voltage range of 2.5 V or 5 V. The
internal reference has an initial accuracy of ±5 mV
and can source or sink up to 20 mA at the
V_REFIN/V_REFOUT pin.
These devices are monotonic, providing excellent
linearity and minimizing undesired code-to-code
transient voltages (glitch). They use a versatile three-
wire serial interface that operates at clock rates up to
50 MHz. The interface is compatible with standard
SPI™, QSPI™, Microwire, and digital signal
processor (DSP) interfaces. The DACxx62-Q1
devices incorporate a power-on-reset circuit that
ensures the DAC output powers up and remains at
zero scale until a valid code is written to the device,
whereas the DACxx63-Q1 devices similarly power up
at mid-scale. These devices contain a power-down
feature that reduces current consumption to typically
550 nA at 5 V. The low power consumption, internal
reference, and small footprint make these devices
ideal for portable, battery-operated equipment.
The DACxx62-Q1 devices are drop-in and function-
compatible with each device in this family, as are the
DACxx63-Q1 devices. The entire family is available in
a 10-pin VSSOP-10 (DGS) package.
