Key Featrues
Wide Supply Range: The OPA548 operates on a wide supply range of 8 V to 60 V for single supply and ±4 V to ±30 V for dual supply, offering design flexibility for various applications. This feature allows the amplifier to be used in both low-voltage and high-voltage systems, enhancing its versatility across different use cases.
High-Output Current Capability: With a continuous output current of 3 A and a peak current of 5 A, the OPA548 can drive a wide variety of loads, including motors, actuators, and other high-current devices. This high-current capability ensures robust performance in demanding applications.
Adjustable Current Limit: The OPA548 provides an adjustable current limit, which can be set from 0 A to 5 A using an external resistor and potentiometer or controlled digitally. This feature protects the amplifier and the load from damage due to overcurrent conditions, improving reliability and safety.
Thermal Shutdown and Indicator: The device includes thermal shutdown protection to prevent damage from overheating, along with a thermal shutdown indicator on the Enable/Status (E/S) pin. This feature ensures safe operation under high-temperature conditions and allows for easy monitoring of the amplifier's thermal status.
Output Disable Control: The OPA548 features an output disable control via the E/S pin, which not only disconnects the load but also reduces quiescent current to conserve power. This is particularly useful in power-sensitive applications, improving energy efficiency and extending battery life in portable devices.
