OPA445  
SBOS156B − MARCH 1987 − REVISED APRIL 2008  
High Voltage FET-Input  
OPERATIONAL AMPLIFIER  
FD EATURES  
DESCRIPTION  
WIDE-POWER SUPPLY RANGE:  
10V to 45V  
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.

HIGH SLEW RATE: 15V/µs  
LOW INPUT BIAS CURRENT: 10pA  
STANDARD-PINOUT TO-99, DIP, SO-8  
PowerPAD, AND SO-8 SURFACE-MOUNT  
PACKAGES  
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 minimiz-  
ing their output loading effects. Laser trimming of the input  
circuitry yields low input offset voltage and drift.

AUDIO  
The OPA445 is available in standard pinout TO-99, DIP-8,  
and SO-8 surface-mount packages as well as an SO-8  
PowerPAD package for reducing junction temperature. 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 (from www.ti.com).
