FEATURES

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_REFOUTpin.

•

Relative Accuracy:

–

DAC856x (16-Bit): 4 LSB INL

DAC816x (14-Bit): 1 LSB INL

DAC756x (12-Bit): 0.3 LSB INL

•

Glitch Energy: 0.1 nV-s

Bidirectional Reference: Input or 2.5-V Output

–

Output Disabled by Default

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.

±5-mV Initial Accuracy (Max)

4-ppm/°C Temperature Drift (Typ)

10-ppm/°C Temperature Drift (Max)

20-mA Sink/Source Capability

•

Power-On Reset to Zero Scale or Mid-Scale

Low-Power: 4 mW (Typ, 5-V AV_DD, Including

Internal Reference Current)

•

Wide Power-Supply Range: 2.7 V to 5.5 V

50-MHz SPI With Schmitt-Triggered Inputs

LDAC and CLR Functions

Output Buffer With Rail-to-Rail Operation

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.

The entire family is available in MSOP-10 and SON-

10 packages.
