GENERAL DESCRIPTION

The AD5725 is a quad, 12-bit, parallel input, voltage output

digital-to-analog converter that offers guaranteed monotonicity,

integral nonlinearity (INL) of ±0.5 LSB maximum and 10 μs

maximum settling time.

Output voltage swing is set by two reference inputs, V

positive voltage, the DAC provides a unipolar positive output

range. 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.

iCMOS® Process Technology

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.

Digital controls allow the user to load or read back data from

any DAC, load any DAC, and transfer data to all DACs at

one time.

The AD5725 is available in a 28-lead SSOP package. 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

from +2.5 V to ±10 V. Power dissipation is less than 270 mW

with ±15 V supplies and only 40 mW with a +5 V supply.

Operation is specified over the temperature range of −40°C

to +85°C.
