DESCRIPTION
The DAC856x, DAC816x, and DAC756x 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 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 devices
incorporate a power-on-reset circuit that ensures the
DAC output powers up at zero scale until a valid code
is written to the device, whereas the DACxx63s
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 DACxx63s.
The entire family is available in MSOP-10 and SON-
10 packages.
