ITPA3116D2 Amplifier Board: Key Features and Specifications

Let's get into the nitty-gritty. What makes the ITPA3116D2 amplifier board so special? Here's a breakdown of its key features and specifications to help you understand what you're getting:

• Power Output: This is a big one. The power output can vary depending on the specific board design and the power supply used. However, you can generally expect anywhere from 50W to 120W per channel. This makes it suitable for powering a range of speakers, from small bookshelf speakers to larger floor-standing models. Keep in mind that the power output is often specified at a certain voltage and impedance, so always check the board's specifications to ensure it meets your needs.
• Efficiency: Class D amplifiers are all about efficiency. The TPA3116D2 chip is incredibly efficient, often achieving efficiencies of 90% or higher. This means less energy is wasted as heat, extending battery life in portable applications and reducing the need for large heat sinks.
• Input Voltage: These boards typically operate on a DC voltage, and the input voltage range can vary. Common ranges include 12V to 24V, but always double-check the board's specifications to ensure compatibility with your power supply.
• Impedance: The impedance of your speakers is critical. Most ITPA3116D2 boards are designed to work with speakers with an impedance of 4 to 8 ohms. Mismatching the impedance can result in poor sound quality or damage to the amplifier.
• Frequency Response: The frequency response tells you the range of frequencies the amplifier can reproduce. The TPA3116D2 generally offers a wide frequency response, meaning it can handle everything from deep bass to clear highs.
• Additional Features: Many boards come with additional features, such as Bluetooth connectivity, which allows you to stream audio wirelessly from your phone or other devices. Some also include tone controls (bass, treble), allowing you to fine-tune the sound to your liking. Others may include a built-in pre-amplifier, which can boost the audio signal before it reaches the amplifier.
• Size and Design: The boards are typically quite compact, making them easy to integrate into various projects. The layout is usually straightforward, with clearly labeled terminals for power, input, and output. This makes it a breeze to connect the board and start using it.

Understanding these features will help you choose the right ITPA3116D2 board for your project and ensure that it meets your audio needs. Now, let’s move on and talk about the price.

ITPA3116D2 Amplifier Board Price: What to Expect

Alright, let’s talk money! The ITPA3116D2 amplifier board is known for being budget-friendly. The price can vary depending on several factors, including the seller, any additional features (like Bluetooth or tone controls), and the quality of the components used. However, you can generally expect to pay somewhere between $5 to $25 for a basic board.

• Basic Boards: These are the most affordable and usually include the TPA3116D2 chip, a few basic components, and terminals for power, input, and output. These are a great starting point if you just need a simple amplifier. The price range usually falls between $5 to $10.
