DAC8820  
SBAS358CAUGUST 2005REVISED JUNE 2006  
16-Bit, Parallel Input Multiplying Digital-to-Analog Converter  
FEATURES  
APPLICATIONS  
Automatic Test Equipment  
Instrumentation  
Digitally Controlled Calibration  
Industrial Control PLCs  
±0.5 LSB DNL  
±1 LSB INL  
16-Bit Monotonic  
Low Noise: 10 nV/Hz  
Low Power: IDD = 2 µA  
Analog Power Supply: +2.7 V to +5.5 V  
DESCRIPTION  
The DAC8820,  
a
multiplying digital-to-analog  
1.66 mA Full-Scale Current,  
with VREF = 10 V  
converter (DAC), is designed to operate from a  
single 2.7 V to 5.5 V supply.  
Settling Time: 0.5 µs  
The applied external reference input voltage VREF  
determines the full-scale output current. An internal  
feedback resistor (RFB  
tracking for the full-scale output when combined with  
an external, current-to-voltage (I/V) precision  
amplifier.  
4-Quadrant Multiplying Reference  
Reference Bandwidth: 8 MHz  
Reference Input: ±15 V  
)
provides temperature  
Reference Dynamics: –105 THD  
SSOP-28 Package  
A
parallel  
interface  
offers  
high-speed  
Industry-Standard Pin Configuration  
communications. The DAC8820 is packaged in a  
space-saving SSOP-28 package and has an  
industry-standard pinout.
