GENERAL DESCRIPTION
The AD5450/AD5451/AD5452/AD54531 are CMOS 8-/10-/12-/
14-bit current output digital-to-analog converters, respectively.
These devices operate from a 2.5 V to 5.5 V power supply,
making them suited to several applications, including battery-
powered applications.
As a result of manufacture on a CMOS submicron process,
these DACs offer excellent 4-quadrant multiplication
characteristics of up to 12 MHz.
These DACs use a double-buffered, 3-wire serial interface that
is compatible with SPI®, QSPI™, MICROWIRE™, and most DSP
interface standards. Upon power-up, the internal shift register
and latches are filled with 0s, and the DAC output is at zero scale.
1 U.S. Patent Number 5,689,257.

The applied external reference input voltage (VREF) determines
the full-scale output current. These parts can handle ±10 V
inputs on the reference, despite operating from a single-supply
power supply of 2.5 V to 5.5 V. An integrated feedback resistor
(RFB) provides temperature tracking and full-scale voltage
output when combined with an external current-to-voltage
precision amplifier.
The AD5450/AD5451/AD5452/AD5453 DACs are available in
small 8-lead TSOT, and the AD5452/AD5453 are also available
in MSOP packages. The AD5453 also comes in 8-lead LFCSP.
The EV-AD5443/46/53SDZ evaluation board is available for
evaluating DAC performance. For more information, see the UG-
327 evaluation board user guide.
