DAC8805

SBAS391A – DECEMBER 2006 – REVISED MAY 2007

14-Bit, Dual, Parallel Input, Multiplying

Digital-to-Analog Converter

• ±0.5LSB DNL

The DAC8805 dual, multiplying digital-to-analog

converter (DAC) is designed to operate from a single

• ±0.5LSB INL

2.7V to 5.5V supply.

• Low Noise: 12nV/√Hz

• Low Power: I

determines the full-scale output current. An internal

• 2mA Full-Scale Current, with V

feedback

resistor

provides

temperature

• Settling Time: 0.5µs

tracking for the full-scale output when combined with

an

external,

current-to-voltage

(I/V)

precision

• 14-Bit Monotonic

amplifier.

• 4-Quadrant Multiplying Reference Inputs

A RSTSEL pin allows system reset assertion (RS) to

• Reference Bandwidth: 10MHz

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

• Reference Input: ±18V

or

to

mid-scale

code

when

RSTSEL

=

'1'.

• Reference Dynamics: –105 THD

Additionally, an internal power-on reset forces all

registers to zero or mid-scale code at power-up,

• Midscale or Zero Scale Reset

depending on the state of the RSTSEL pin.

• Analog Power Supply: +2.7V to +5.5V

A

parallel

interface

offers

high-speed

• TSSOP-38 Package

communications. The DAC8805 is packaged in a

• Industry-Standard Pin Configuration

space-saving

TSSOP-38

package

and

has

an

• Pin Compatible with the 16-Bit DAC8822

industry-standard pinout. The device is specified

from –40

°C to +125°C.

• Temperature Range: –40°C to +125°C

pin-compatible

version,
