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 excellent
low-level signal accuracy and high output voltage and cur-
rent.
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.
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 鈥減ower鈥?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 150碌A(chǔ) 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 current
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 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,
鈥?0擄C to +85擄C.
