HIGH POWER, HIGH CURRENT
OPERATIONAL AMPLIFIER
8-Pin, TO-3 And DIP, 10 Amp Monolithic Power
Operational Amplifier
FEATURES
• Available In Isolated Standard TO-3, “Copper Slug” TO-3 And
Power DIP Packages
• 10 Amp Peak Output Current
• Power Supplies to ±40V
• Programmable Current Limit
• FET Input
• Available Screened to MIL-STD-883
DESCRIPTION
The OMA541 is a power operational amplifier capable of operation from power
supplies up to ±40V and continuous output current up to 5A. Internal current limit
circuitry can be user-programmed with a single external resistor, protecting the
amplifier and load from fault conditions. The OMA541 pinout is compatible with
popular power operational amplifiers such as the OPA511, OPA512 and OPA3573.
This device is ideally suited for Military motor driver, servo amplifier, synchro
exertation as well as other power drive circuitry. The OMA541SKC incorporates a
copper slug to the header for improved thermal performance.
