3 Description
The OPA548 device is a low-cost, high-voltage and
high-current operational amplifier that's 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
current.
The OPA548 device operates from either single or
dual supplies for design flexibility. In single-supply
operation, the input common-mode range extends
below ground.
The OPA548 device is internally protected against
over-temperature conditions and current overloads. In
addition, the OPA548 device 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 OPA548 device senses the
load indirectly. This allows the current limit to be
adjusted from 0 A to 5 A with a resistor and
potentiometer or controlled digitally with a voltage-out
or current-out DAC.
