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 technology1 that offers
guaranteed monotonicity and integral nonlinearity (INL)
of ±1 LSB maximum.
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 DSPand 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.
