Description
The DAC756x, DAC816x, and DAC856x devices are
low-power, voltage-output, dual-channel, 16-, 14-,
and 12-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 VREFIN/VREFOUT 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 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 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 devices are drop-in and function
compatible with each other, as are the DACxx63
devices. The entire family is available in MSOP-10
and SON-10 packages.
