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, VREFP and
VREFN. By setting the VREFN input to 0 V and the VREFP to a
positive voltage, the DAC provides a unipolar positive output
range. A similar configuration with VREFP at 0 V and VREFN at a
negative voltage provides a unipolar negative output range.
Bipolar outputs are configured by connecting both VREFP and
VREFN to 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.

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.
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.

1 For single supply operation only (VREFN = 0 V, AVSS = 0 V): Due to internal offset errors, INL and DNL are measured beginning at code 0x005.
2 Guaranteed by design and characterization, not production tested.
3 Operation is guaranteed over this reference range, but linearity is neither tested nor guaranteed.
