DAC8822

SBAS390A – DECEMBER 2006 – REVISED MARCH 2007

16-Bit, Dual, Parallel Input, Multiplying

Digital-to-Analog Converter

• ±0.5LSB DNL

The DAC8822 dual, multiplying digital-to-analog

converter (DAC) is designed to operate from a single

• ±1LSB INL

2.7V to 5.5V supply.

• Low Noise: 12nV/√Hz

• Low Power Operation:

determines the full-scale output current. An internal

feedback

resistor

provides

temperature

• 2mA Full-Scale Current, with V

tracking for the full-scale output when combined with

• Settling Time: 0.5µs

an

external,

current-to-voltage

(I/V)

precision

amplifier.

• 16-Bit Monotonic

• 4-Quadrant Multiplying Reference Inputs

A RSTSEL pin allows system reset assertion (RS) to

force all registers to zero code when RSTSEL = '0',

• Reference Bandwidth: 10MHz

or to midscale code when RSTSEL = '1'. Additionally,

• Reference Input: ±18V

an internal power-on reset forces all registers to zero

• Reference Dynamics: –105 THD

or midscale code at power-up, depending on the

state of the RSTSEL pin.

• Midscale or Zero Scale Reset

• Analog Power Supply: +2.7V to +5.5V

A

parallel

interface

offers

high-speed

communications. The DAC8822 is packaged in a

• TSSOP-38 Package

space-saving

TSSOP-38

package

and

has

an

• Industry-Standard Pin Configuration

industry-standard pinout. The device is specified

• Pin-Compatible with the 14-Bit DAC8805

from –40

°C to +125°C.

• Temperature Range: –40°C to +125°C
