SBOS070B – OCTOBER 1997 – OCTOBER 2003  
High-Voltage, High-Current  
OPERATIONAL AMPLIFIER  
DESCRIPTION  
FEATURES  
The OPA548 is a low-cost, high-voltage/high-current opera-  
● WIDE SUPPLY RANGE  
Single Supply: +8V to +60V  
Dual Supply: ±4V to ±30V  
tional amplifier ideal for driving a wide variety of loads. A  
laser-trimmed monolithic integrated circuit provides excellent  
low-level signal accuracy and high output voltage and cur-  
rent.  
● HIGH OUTPUT CURRENT:  
3A Continuous  
5A Peak  
The OPA548 operates from either single or dual supplies for  
design flexibility. In single-supply operation, the input com-  
mon-mode range extends below ground.  
● WIDE OUTPUT VOLTAGE SWING  
● FULLY PROTECTED:  
Thermal Shutdown  
The OPA548 is internally protected against over-temperature  
conditions and current overloads. In addition, 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 0A 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, Zip and Straight Leads  
7-Lead DDPAK Surface-Mount  
APPLICATIONS  
● VALVE, ACTUATOR DRIVERS  
● SYNCHRO, SERVO DRIVERS  
● POWER SUPPLIES  
The OPA548 is available in an industry-standard  
7-lead staggered and straight lead 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.
