DESCRIPTION  
The OPA445 is a monolithic operational amplifier  
capable of operation from power supplies up to ±45V  
and output currents of 15mA. It is useful in a wide  
variety of applications requiring high output voltage  
or large common-mode voltage swings.  
mizing their output loading effects. Laser trimming of  
the input circuitry yields low input offset voltage and  
drift.  
The OPA445 is available in standard pin-out TO-99,  
DIP-8, and SO-8 surface-mount packages. It is fully  
specified from –25°C to +85°C and operates from  
–55°C to +125°C. A SPICE macromodel is available  
for design analysis.  
The OPA445’s high slew rate provides wide power-  
bandwidth response, which is often required for high-  
voltage applications. FET input circuitry allows the  
use of high-impedance feedback networks, thus mini-
