DESCRIPTION

The OPA547 is a low cost, high-voltage/high-current opera-

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

laser-trimmed monolithic integrated circuit provides excel-

lent low-level signal accuracy and high output voltage and

current.

The OPA547 operates from either single or dual supplies for

design flexibility. In single supply operation, the input

common-mode range extends below ground.

The OPA547 is internally protected against over-tempera-

ture 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 0 to 750mA with a 0 to 150µA control signal.

This is easily done with a resistor/potentiometer or con-

trolled digitally with a voltage-out or current-out DAC.

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 quies-

cent to conserve power. The E/S pin output can be moni-

tored to determine if the OPA547 is in thermal shutdown.

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.
