● LOW INPUT BIAS CURRENT: –1.2µA  
The feedback buffer stage provides 700MHz band-  
width, a very high slew rate, and a very short signal  
delay time. It is designed primarily for interstage  
buffering and not for driving long cables. When com-  
bined with the current-feedback amplifier section, the  
OPA622 can be interconnected as a voltage-feedback  
amplifier with two identical high-impedance inputs.  
In this configuration, it features a low common-mode  
gain, low input offset, and, due to the delay time of the  
additional feedback buffer, a decrease in frequency  
bandwidth compared with the current-feedback  
configuration. Unlike “classical” operational amplifi-  
ers, the OPA622 achieves a nearly constant bandwidth  
over a wide gain and output voltage range. The  
external setting of the open-loop gain with ROG avoids  
a large compensation capacitor, improves the slew  
rate, and allows a frequency response adaption to  
various gains and load conditions.  
DESCRIPTION  
The OPA622 is a monolithic amplifier component  
designed for precision wide-bandwidth systems  
including high-resolution video, RF and IF circuitry,  
and communications equipment. It includes a mono-  
lithic integrated current-feedback operational  
amplifier block and a voltage buffer block, which,  
when combined, form a voltage-feedback operational  
amplifier.  
When combined as a current-feedback amplifier, it  
provides a 280MHz large-signal bandwidth at ±2.5V  
output level and a 1700V/µs slew rate. The output  
buffer stage can deliver ±70mA output current. The  
high output current capability allows the OPA622 to  
drive two 50Ω or 75Ω lines with ±3V output swing,  
making it ideal along with the low differential  
gain/phase errors for RF, IF, and video applications.
