Understanding Ferrite Inductors in Class D Amplifier Design: Class D audio amplifiers continue to grow in popularity, powering everything from portable Bluetooth speakers to high-performance home audio systems. Their appeal is clear: they’re efficient, compact, and capable of delivering impressive sound. But behind every great Class D amplifier is one small component that plays a big role — the output inductor. Our latest application note introduces designers to how ferrite-based inductors fit into the Class D signal path and why they matter. Whether you’re new to Class D technology or simply exploring ways to get better audio performance, this guide offers a friendly, approachable overview of the fundamentals.

Why Focus on the Output Inductor?

In a Class D amplifier, the output inductor helps turn the amplifier’s high-frequency switching signal into clean, listenable audio. While that function sounds simple, choosing the right inductor can influence:

• Sound quality
• Power efficiency
• Thermal performance
• EMI behavior

Our application note walks through these ideas in a clear and accessible way — no heavy equations required.

What You’ll Learn in the Application Note

The document gives readers a practical look at:

• The role of ferrite materials in audio designs
• How inductors help maintain clean, stable audio output
• What matters most when selecting an inductor for a Class D amplifier
• A real-world example using a popular 150 W design

It’s a great starting point for engineers, product designers, and anyone who wants to understand the building blocks behind modern audio systems.

Need a better way to sense current on busbars? Let's revisit the ISB Series Current Sense Transducer. This compact sensor is a smart alternative to bulky, traditional sensors. It delivers high performance with fast response and high bandwidth. A custom ASIC-based Hall effect device powers the ISB series. It operates without a traditional core and winding. This core-less design is the key to provide a lower-cost solution. It delivers fast response, high bandwidth, high isolation, and performance sitting between open-loop and closed-loop designs. It's designed for currents from 75 A up to over 670 A and is easy to install in applications with tight dimensional constraints.

Key Design Features You Can Leverage

Our ISB Series App Note (ISB-AN1-R1) details the ISB’s smart features. These features solve common engineering challenges.

• Concentrates Magnetic Flux: The shield provides a path of lower magnetic resistance. This concentrates the magnetic flux density. This helps the sensor measure low current levels.
• Protects from EMI: The shield also helps protect the sensor from stray EMI fields from adjacent high-current paths.

Total Design Flexibility

The ISB series is built for easy integration:

• Connection Options: Choose between a compact header connector (8.5 mm creepage) or a lead-wire version (158.5 mm creepage) for much higher isolation.
• Programmable Ranges: We can factory program custom current ranges. This includes unsymmetrical ranges (e.g., -100 A to +300 A).
• Simplified Integration: A reference output is available, providing a stable voltage at 50% of V_DD to simplify driving an op-amp circuit.
