OPA549

SBOS093E – MARCH 1999 – REVISED OCTOBER 2005

High-Voltage, High-Current

OPERATIONAL AMPLIFIER

DESCRIPTION

FEATURES

The OPA549 is a low-cost, high-voltage/high-current opera-

tional amplifier ideal for driving a wide variety of loads. This

laser-trimmed monolithic integrated circuit provides excellent

low-level signal accuracy and high output voltage and current.

● HIGH OUTPUT CURRENT:

8A Continuous

10A Peak

● WIDE POWER-SUPPLY RANGE:

Single Supply: +8V to +60V

Dual Supply: ±4V to ±30V

The OPA549 operates from either single or dual supplies for

design flexibility. The input common-mode range extends

below the negative supply.

● WIDE OUTPUT VOLTAGE SWING

The OPA549 is internally protected against over-temperature

conditions and current overloads. In addition, the OPA549

provides an accurate, user-selected current limit. Unlike

other designs which use a “power” resistor in series with the

output current path, the OPA549 senses the load indirectly.

This allows the current limit to be adjusted from 0A to 10A

with a resistor/potentiometer, or controlled digitally with a

voltage-out or current-out Digital-to-Analog Converter (DAC).

● FULLY PROTECTED:

Thermal Shutdown

Adjustable Current Limit

● OUTPUT DISABLE CONTROL

● THERMAL SHUTDOWN INDICATOR

● HIGH SLEW RATE: 9V/µs

● CONTROL REFERENCE PIN

● 11-LEAD POWER PACKAGE

The Enable/Status (E/S) pin provides two functions. It can be

monitored to determine if the device is in thermal shutdown,

and it can be forced low to disable the output stage and

effectively disconnect the load.

APPLICATIONS

● VALVE, ACTUATOR DRIVERS

● SYNCHRO, SERVO DRIVERS

● POWER SUPPLIES

The OPA549 is available in an 11-lead power package. Its

copper tab allows easy mounting to a heat sink for excellent

thermal performance. Operation is specified over the ex-

tended industrial temperature range, –40°C to +85°C.

● TEST EQUIPMENT

● TRANSDUCER EXCITATION

● AUDIO POWER AMPLIFIERS
