Description and Introduction

High-Voltage, High-Current Op Amp with shutdown capability 7-DDPAK/TO-263 -40 to 85 The **OPA547FKTWTG3** is a high-performance operational amplifier (op-amp) designed for precision applications requiring high output current and robust thermal performance. Manufactured by Texas Instruments, this component integrates a wide supply voltage range (±4V to ±30V) with a high output current capability of up to 750mA, making it suitable for driving demanding loads such as motors, transducers, and power supplies.  

Featuring a low offset voltage and low noise, the OPA547FKTWTG3 ensures accurate signal amplification in industrial, automotive, and instrumentation systems. Its built-in thermal shutdown and current-limiting protection enhance reliability in harsh operating conditions. The device is housed in a thermally efficient **TO-263-7 (DDPAK)** package, optimizing heat dissipation for sustained high-power operation.  

With a bandwidth of 1MHz and a slew rate of 6V/µs, this op-amp balances speed and stability, catering to both DC and low-frequency AC applications. Its adjustable current limit allows designers to tailor performance to specific circuit requirements, improving flexibility and system safety.  

Engineers favor the OPA547FKTWTG3 for its robust design, precision, and ability to handle high-power loads—key attributes for applications demanding durability and accuracy.

Application Scenarios & Design Considerations

High-Voltage, High-Current Op Amp with shutdown capability 7-DDPAK/TO-263 -40 to 85

Alternative Part Number

  • OPA548T --: Same TI high-current op-amp family with higher output current capability and similar voltage/current ratings, often used as a drop-in upgrade in power op-amp designs.
  • LM675T --: Classic high-current power op-amp in TO-220 package with comparable supply range and output drive, widely used as a functional substitute for OPA547 in driver applications.
  • OPA544T --: High-voltage, high-current power op-amp from TI with similar package and electrical characteristics, suitable when OPA547 availability is limited.
