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.  
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.  
As a result of manufacture on a CMOS submicron process,  
these DACs offer excellent 4-quadrant multiplication  
characteristics of up to 12 MHz.  
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.  
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.  
The EV-AD5443/46/53SDZ evaluation board is available for  
evaluating DAC performance. For more information, see the UG-  
327 evaluation board user guide.
