High-Voltage, High-Current  
OPERATIONAL AMPLIFIER  
DESCRIPTION  
FEATURES  
The OPA548 is a low cost, high-voltage/high-current  
operational amplifier ideal for driving a wide variety  
of loads. A laser-trimmed monolithic integrated cir-  
cuit provides excellent low-level signal accuracy and  
high output voltage and current.  
● WIDE SUPPLY RANGE  
Single Supply: +8V to +60V  
Dual Supply: ±4V to ±30V  
● HIGH OUTPUT CURRENT:  
3A Continuous  
The OPA548 operates from either single or dual sup-  
plies for design flexibility. In single supply operation,  
the input common-mode range extends below ground.  
5A Peak  
● WIDE OUTPUT VOLTAGE SWING  
● FULLY PROTECTED:  
Thermal Shutdown  
The OPA548 is internally protected against over-  
temperature conditions and current overloads. In addi-  
tion, the OPA548 was designed to provide an accurate,  
user-selected current limit. Unlike other designs which  
use a “power” resistor in series with the output current  
path, the OPA548 senses the load indirectly. This  
allows the current limit to be adjusted from 0 to 5A  
with a resistor/potentiometer or controlled digitally  
with a voltage-out or current-out DAC.  
Adjustable Current Limit  
● OUTPUT DISABLE CONTROL  
● THERMAL SHUTDOWN INDICATOR  
● HIGH SLEW RATE: 10V/µs  
● LOW QUIESCENT CURRENT  
● PACKAGES:  
The Enable/Status (E/S) pin provides two functions.  
An input on the pin not only disables the output stage  
to effectively disconnect the load but also reduces the  
quiescent current to conserve power. The E/S pin  
output can be monitored to determine if the OPA548  
is in thermal shutdown.  
7-Lead TO-220  
7-Lead DDPAK Surface-Mount  
APPLICATIONS  
● VALVE, ACTUATOR DRIVER  
● SYNCHRO, SERVO DRIVER  
● POWER SUPPLIES  
The OPA548 is available in an industry-standard  
7-lead staggered TO-220 package and a 7-lead DDPAK  
surface-mount plastic power package. The copper tab  
allows easy mounting to a heat sink or circuit board  
for excellent thermal performance. It is specified for  
operation over the extended industrial temperature  
range, –40°C to +85°C. A SPICE macromodel is  
available for design analysis.
