3 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 functioncompatible

with each other, as are the DACxx63

devices. The entire family is available in MSOP-10

and SON-10 packages.
