GENERAL DESCRIPTION

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

digital-to-analog converter (DAC) fabricated on Analog

Devices, Inc., iCMOS® process technology

guaranteed monotonicity and integral nonlinearity (INL)

of ±1 LSB maximum.

Output voltage swing is set by two reference inputs, V

For analog systems designers within industrial/instrumentation equipment OEMs who need high performance ICs at higher voltage levels, iCMOS is a technology

platform that enables the development of analog ICs capable of 30 V and operating at ±15 V supplies while allowing dramatic reductions in power consumption and

package size, and increased ac and dc performance.

voltage. A similar configuration with V

negative voltage provides a unipolar negative output range.

Bipolar outputs are configured by connecting both V

ranges has advantages over the bipolar offsetting methods

because it is not dependent on internal and external resistors

with different temperature coefficients.

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

30 MHz and is compatible with DSP and microcontroller interface

standards. The asynchronous CLR function clears all DAC

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

The AD5726 is available in 16-lead SSOP, 20-lead SSOP, and

16-lead SOIC 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.

A similar device, also available from Analog Devices is

the AD5725, which is a quad, 12-bit, parallel input, unipolar/

bipolar, voltage output DAC.
