Quad, 12-Bit, Serial Input,

Unipolar/Bipolar, Voltage Output DAC

AD5726

Bipolar outputs are configured by connecting both V_REFPand

V_REFNto nonzero voltages. This method of setting output voltage

ranges has advantages over the bipolar offsetting methods

because it is not dependent on internal and external resistors

with different temperature coefficients.

FEATURES

+5 V to 15 V operation

Unipolar or bipolar operation

1 ꢀSB maximum INꢀ error, 1 ꢀSB maximum DNꢀ error

Guaranteed monotonic over temperature

Double-buffered inputs

Simultaneous updating via ꢀDAC

Asynchronous CꢀR to zero scale/midscale

Operating temperature range: −40°C to +125°C

iCMOS® process technology¹

The AD5726 uses a serial interface that operates at clock rates up to

30 MHz and is compatible with DꢀP and microcontroller interface

standards. Double buffering allows simultaneous updating of all

CLR

DACs. The asynchronous

function clears all DAC registers

to a user-selectable, zero-scale or midscale output.

The AD5726 is available in 16-lead ꢀꢀOP and 16-lead ꢀOIC

packages. It can be operated from a wide variety of supply and

reference voltages with supplies ranging from single +5 V to

15 V, and references ranging from +2.5 V to 10 V. Power

dissipation is less than 240 mW with 15 V supplies and only

30 mW with a +5 V supply. Operation is specified over the

temperature range of −40°C to +125°C.

APPꢀICATIONS

Industrial automation

Closed-loop servo control, process control

Automotive test and measurement

Programmable logic controllers

GENERAꢀ DESCRIPTION

The AD5726 is a quad, 12-bit, serial input, voltage output

digital-to analog converter that offers guaranteed monotonicity

and integral nonlinearity (INL) of 1 LꢀB maximum.

Description

AD5725

Quad, 12-bit, parallel input,

Output voltage swing is set by two reference inputs, V_REFPand

unipolar/bipolar, voltage output DAC.

V_REFN. The DAC offers a unipolar positive output range when

the V_REFNinput is set to 0 V and the V_REFPinput is set to a positive

voltage. A similar configuration with V_REFPat 0 V and V_REFNat a

negative voltage provides a unipolar negative output range.
