DESCRIPTION
The DAC856x, DAC816x, and DAC756x are low-
23
• Relative Accuracy:
power, voltage-output, dual-channel, 16-, 14-, and 12-
– DAC856x (16-Bit): 4 LSB INL
bit digital-to-analog converters (DACs), respectively.
– DAC816x (14-Bit): 1 LSB INL
These devices include a 2.5-V, 4-ppm/°C internal
reference, giving a full-scale output voltage range of
– DAC756x (12-Bit): 0.3 LSB INL
2.5 V or 5 V. The internal reference has an initial
• Glitch Energy: 0.1 nV-s
accuracy of ±5 mV and can source or sink up to

pin.
– Output Disabled by Default
These devices are monotonic, providing excellent
– ±5-mV Initial Accuracy (Max)
linearity and minimizing undesired code-to-code
transient voltages (glitch). They use a versatile three-
– 4-ppm/°C Temperature Drift (Typ)
wire serial interface that operates at clock rates up to
– 10-ppm/°C Temperature Drift (Max)
50 MHz. The interface is compatible with standard
– 20-mA Sink/Source Capability
SPI™, QSPI™, Microwire™, and digital signal
processor (DSP) interfaces. The DACxx62 devices
• Power-On Reset to Zero Scale or Mid-Scale
incorporate a power-on-reset circuit that ensures the

is written to the device, whereas the DACxx63s
• Wide Power-Supply Range: 2.7 V to 5.5 V
similarly power up at mid-scale. These devices
contain a power-down feature that reduces current
• 50-MHz SPI With Schmitt-Triggered Inputs
consumption to typically 550 nA at 5 V. The low

footprint make these devices ideal for portable,
battery-operated equipment.
• Packages: SON-10 (3x3 mm), MSOP-10
• Temperature Range: –40°C to 125°C
The DACxx62 devices are drop-in and function-
compatible with each other, as are the DACxx63s.
APPLICATIONS The entire family is available in MSOP-10 and SON-
10 packages.
