OPA547

SBOS056F – JANUARY 2002 – JULY 2005

High-Voltage, High-Current

OPERATIONAL AMPLIFIER

DESCRIPTION

FEATURES

The OPA547 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:

500mA Continuous

The OPA547 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 OPA547 is internally protected against over-temperature

conditions and current overloads. In addition, 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 0mA 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, Zip and Straight Leads

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 current

to conserve power. The E/S pin output can be monitored to

determine if the OPA547 is in thermal shutdown.

APPLICATIONS

● VALVE, ACTUATOR DRIVERS

● SYNCHRO, SERVO DRIVERS

● POWER SUPPLIES

The OPA547 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.

● TEST EQUIPMENT

● TRANSDUCER EXCITATION

● AUDIO AMPLIFIERS
