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 150 A 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.

APPLICATIONS INFORMATION Figure 1 shows the OPA547 connected as a basic non- inverting amplifier. The OPA547 can be used in virtually any op amp configuration. Power supply terminals should be bypassed with low series impedance capacitors. The technique shown, using ...

THERMAL PROTECTION The OPA547 has thermal shutdown that protects the ampli- fier from damage. Activation of the thermal shutdown cir- cuit during normal operation is an indication of excessive power dissipation or an inadequate heat sink. Depending on load and ...
