DESCRIPTION
The OPA561 is a low-cost, high-current operational
amplifier capable of driving up to 1.2A pulses into reactive
loads. This monolithic integrated circuit provides high
reliability in demanding line-carrier communications, laser
diode drivers, and motor control applications. The high
slew rate provides 1MHz full-power bandwidth and
excellent linearity.
The OPA561 operates from either a single supply in the
range of 7V to 15V or dual power supplies of
鹵3.5V
to
鹵7.5V
for design flexibility. In single-supply operation, the
input common-mode range extends below ground. At
maximum output current, a wide output swing provides a
12Vp-p capability with a nominal 15V supply.
The OPA561 is internally protected against over-
temperature conditions and current overloads. In addition,
the OPA561 is designed to provide an accurate, user-
selected, current limit. The current limit can be adjusted
from 0.2A to 1.2A with a low-power resistor/potentiometer
or DAC (Digital-to-Analog Converter). The high-speed
characteristics of the current control loop provide accuracy
even under pulsed load conditions.
The Enable/Status (E/S) pin performs two functions: it can
be monitored to determine if the device is in thermal
shutdown (active LOW), and it can also be forced LOW to
disable the output, disconnecting the load.
The OPA561 is available in the miniature, HTSSOP-20
PowerPAD錚?power package. This surface-mount pack-
age is thermally enhanced and has a very low thermal
resistance. Operation is specified over the extended
industrial temperature range, 鈭?0_C to +125_C.
