OPA547

High-Voltage, High-Current

OPERATIONAL AMPLIFIER

DESCRIPTION

FEATURES

The OPA547 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:

500mA Continuous

The OPA547 operates from either single or dual sup-

plies for design flexibility. In single supply operation,

the input common-mode range extends below ground.

● WIDE OUTPUT VOLTAGE SWING

● FULLY PROTECTED:

Thermal Shutdown

The OPA547 is internally protected against over-

temperature conditions and current overloads. In addi-

tion, the OPA547 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 OPA547 senses the load indirectly. This

allows the current limit to be adjusted from 0 to

750mA with a 0 to 150µA control signal. This is easily

done with a resistor/potentiometer or controlled digi-

tally with a voltage-out or current-out DAC.

Adjustable Current Limit

● OUTPUT DISABLE CONTROL

● THERMAL SHUTDOWN INDICATOR

● HIGH SLEW RATE: 6V/µs

● LOW QUIESCENT CURRENT

● PACKAGES:

7-Lead TO-220

7-Lead DDPAK Surface-Mount

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 to conserve power. The E/S pin output can

be monitored to determine if the OPA547 is in thermal

shutdown.

APPLICATIONS

● VALVE, ACTUATOR DRIVER

● SYNCHRO, SERVO DRIVER

● POWER SUPPLIES

The OPA547 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.

● TEST EQUIPMENT

● TRANSDUCER EXCITATION
