DAC8881

SBAS422A–JULY 2007–REVISED SEPTEMBER 2007

16-Bit, Single-Channel, Low-Noise, Voltage-Output

DIGITAL-TO-ANALOG CONVERTER

FEATURES

DESCRIPTION

2345

•

Relative Accuracy: ±0.5 LSB

16-Bit Monotonic Over Temperature Range

Low-Noise: 24nV/√Hz

The DAC8881 is

16-bit, single-channel,

voltage-output digital-to-analog converter (DAC) that

offers low-power operation and a flexible SPI serial

interface. It also features 16-bit monotonicity,

excellent linearity, and fast settling time. The on-chip

precision output amplifier allows rail-to-rail output

swing to be achieved over the full supply range of

2.7V to 5.5V.

•

Fast Settling: 5μs

On-Chip Output Buffer Amplifier with

Rail-to-Rail Operation

•

Wide, Single Power Supply: +2.7V to +5.5V

DAC Loading Control

The device supports a standard SPI serial interface

capable of operating with input data clock frequencies

up to 50MHz. The DAC8881 requires an external

reference voltage to set the output range of the DAC

channel. A programmable power-on reset circuit is

also incorporated into the device to ensure that the

DAC output powers up at zero-scale or midscale, and

remains there until a valid write command.

Selectable Power-On Reset to Zero-Scale or

Midscale

•

Power-Down Mode

Unipolar Straight Binary or

2's Complement Input Mode

•

Fast SPI™ Interface with Schmitt-Triggered

Inputs:

Up To 50MHz, 1.8V/3V/5V Logic

Additionally, the device has the capability to function

in either unipolar straight binary or 2's complement

mode. The DAC8881 provides a power-down feature,

accessed over the PDN pin, that reduces the current

consumption to 25μA at 5V. Power consumption is

6mW at 5V, reducing to 125μW in power-down mode.

Small Package: QFN-24, 4x4mm
