GENERAL 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 LSB maximum.
www.DataSheet4U.com Output voltage swing is set by two reference inputs, VREFP and
VREFN. The DAC offers a unipolar positive output range when
the VREFN input is set to 0 V and the VREFP input is set to a positive
voltage. 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.
The AD5726 uses a serial interface that operates at clock rates up to
30 MHz and is compatible with DSP and microcontroller interface
standards. Double buffering allows simultaneous updating of all
DACs. 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 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.

1 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.
