12-/14-Bit High Bandwidth  
Multiplying DACs with Serial Interface  
AD5444/AD5446  
GENERAL DESCRIPTION  
FEATURES  
12 MHz multiplying bandwidth  
INL of 0.ꢀ LSB at 12 bits  
Pin-compatible 12-/14-bit current output DAC  
2.ꢀ V to ꢀ.ꢀ V supply operation  
10-lead MSOP package  
10 V reference input  
ꢀ0 MHz serial interface  
2.7 MSPS update rate  
The AD5444/AD54461 are CMOS 12-bit and 14-bit, current  
output, digital-to-analog converters (DACs). Operating from a  
single 2.5 V to 5.5 V power supply, these devices are suited for  
battery-powered and other applications.  
As a result of the CMOS submicron manufacturing process,  
these parts offer excellent 4-quadrant multiplication char-  
acteristics 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. On power-up, the internal shift register and  
latches are filled with 0s, and the DAC output is at zero scale.  
Extended temperature range: −40°C to +12ꢀ°C  
4-quadrant multiplication  
Power-on reset with brownout detection  
0.4 μA typical current consumption  
Guaranteed monotonic  
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 AD5444/AD5446 DACs are available in small  
10-lead MSOP packages, which are pin-compatible with the  
AD5425/AD5426/AD5432/AD5443 family of DACs.  
APPLICATIONS  
Portable, battery-powered applications  
Waveform generators  
Analog processing  
Instrumentation applications  
Programmable amplifiers and attenuators  
Digitally controlled calibration  
Programmable filters and oscillators  
Composite video
