DESCRIPTION
The OPA549 is a low-cost, high-voltage/high-current
operational amplifier ideal for driving a wide variety
of loads. This laser-trimmed monolithic integrated
circuit provides excellent low-level signal accuracy,
and high output voltage and current.
The OPA549 operates from either single or dual sup-
plies for design flexibility. The input common-mode
range extends below the negative supply.
The OPA549 is internally protected against over-
temperature conditions and current overloads. In addi-
tion, the OPA549 provides an accurate, user-selected
current limit. Unlike other designs which use a 鈥減ower鈥?/div>
resistor in series with the output current path, the
OPA549 senses the load indirectly. This allows the
current limit to be adjusted from 0A to 10A with a
resistor/potentiometer, or controlled digitally with a
voltage-out or current-out DAC.
The Enable/Status (E/S) pin provides two functions. It
can be monitored to determine if the device is in
thermal shutdown, and it can be forced low to disable
the output stage and effectively disconnect the load.
The OPA549 is available in an 11-lead power ZIP
package. Its copper tab allows easy mounting to a heat
sink for excellent thermal performance. Operation is
specified over the extended industrial temperature
range, 鈥?0擄C to +85擄C.
