## Summary description

Texas Instruments OPA547T is a single‑channel operational amplifier with low total harmonic distortion (THD 0.004%). Supplied in a package measuring 532.1 × 34.5 × 13.3 mm, it suits applications requiring precise analog amplification and low distortion, such as audio preamplifiers, instrumentation front ends, and laboratory power amplifiers.

## Long description

Texas Instruments OPA547T is a single‑channel operational amplifier designed for high-voltage, high-current applications that require low total harmonic distortion (THD 0.004%). The device is provided in a package measuring 532.1 × 34.5 × 13.3 mm and features laser‑trimmed monolithic circuitry for accurate low‑level signal amplification, high output voltage and current capability, and internal protection against over‑temperature and current overloads. The amplifier supports single or dual supply operation with an input common‑mode range that extends below ground in single‑supply mode, making it suitable for a wide range of analog front‑end and power amplification tasks.
Advantages
The OPA547T combines low distortion performance with high output drive and adjustable current limiting, enabling precise analog amplification while protecting the device and the load. Internal thermal and overload protection reduce the need for external circuitry, and the Enable/Status pin provides both output disable and system‑monitoring capability. The package includes a copper tab for straightforward heat‑sink mounting to maintain thermal performance in demanding conditions.
Suitable for
Audio preamplifiers and analog signal processing with low distortion requirements
Instrumentation front ends and laboratory amplifiers requiring stable, accurate amplification
Power amplifier stages and load‑driving applications that need high output current
Circuits where adjustable current limiting and thermal status monitoring are required
Key specifications
Single‑channel operational amplifier
Total harmonic distortion: 0.004%
Package dimensions: 532.1 × 34.5 × 13.3 mm
High output voltage and high output current capability
Operates from single or dual supplies; input common‑mode range extends below ground in single‑supply operation
Adjustable current limit: user‑settable from 0 mA to 750 mA via a 0 to 150 µA control signal
Internal thermal shutdown and current overload protection
Enable/Status (E/S) pin: output disable and thermal‑shutdown status monitoring
Copper tab for heat‑sink or board mounting to improve thermal performance
Specified for extended industrial temperature operation (–40°C to +85°C)
How to use
Integrate the OPA547T into the amplifier stage following standard analog layout practices: provide appropriate supply bypassing, ensure the copper tab is mounted to a heat sink or board area capable of dissipating heat for high‑power operation, and configure the input and feedback network for the desired gain and bandwidth. Set the adjustable current limit using a resistor or potentiometer tied to the current‑limit control input, or drive that control with a DAC for digital adjustment. Use the Enable/Status pin to disable the output and reduce quiescent current when the amplifier is not required, and monitor the E/S output to detect thermal shutdown events.
Usage recommendations
For reliable performance, use proper thermal management when operating near the amplifier’s current or voltage limits, place supply decoupling capacitors close to the device pins, and follow layout guidelines to minimize oscillation and noise. When implementing the adjustable current limit, verify the control‑signal range and test the limit under expected load conditions before finalizing the design.
