OPA820  
SBOS303D –JUNE 2004–REVISED DECEMBER 2016  
OPA820 Unity-Gain Stable, Low-Noise, Voltage-Feedback Operational Amplifier  
1 Features  
3 Description  
The OPA820 device provides a wideband, unity-gain  
stable, voltage-feedback amplifier with a very-low  
input-noise voltage and high-output current using a  
low 5.6-mA supply current. At unity-gain, the OPA820  
device gives more than 800-MHz bandwidth with less  
than 1-dB peaking. The OPA820 device complements  
this high-speed operation with excellent DC precision  
in a low-power device. A worst-case input-offset  
voltage of ±750 µV and an offset current of ±400 nA  
provide excellent absolute DC precision for pulse  
amplifier applications.

Maximum 25°C Input Offset Voltage = ±750 µV  
Maximum 25°C Input Offset Current = ±400 nA  
Minimal input and output voltage-swing headroom  
allow the OPA820 device to operate on a single 5-V  
supply with more than 2-VPP output swing. While not  
a rail-to-rail (RR) output, this swing supports most  
emerging analog-to-digital converter (ADC) input  
ranges with lower power and noise than typical RR  
output op amps.
