High-Voltage, High-Current
OPERATIONAL AMPLIFIER
DESCRIPTION
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.
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.
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 150
μ
A control signal. This is easily
done with a resistor/potentiometer or controlled digi-
tally 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
quiescent to conserve power. The E/S pin output can
be monitored 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.
