The development of modern silicon technology has given a second life to class D amplifiers. The circuitry of these amplifiers provides a significantly higher damping coefficient in comparison with class AB and other circuitry solutions. This not only guarantees stable operation with complex loads, fast, clear bass and a large dynamic range, but also provides a lower level of distortion, the absence of porridge, a sluggish attack or blurring of the fronts, and most importantly, the amplifier’s ability to equally cope with completely diverse music.
Introducing another high-end Class-D amplifier on the TPA3116D2 chip from Texas Instruments.
The advantages of this amplifier:
- the radiator is mounted on screws, in contrast to cheaper options on hotmelt;
- competent circuit solutions, their compliance with the requirements of technical documents, high quality components;
- low consumption at rest;
- high efficiency, the ability to work with a standard heat sink;
- the ability to work with low voltage power supplies;
- ease of connection and installation in any design;
- small dimensions and weight of the entire board assembly.
Supply voltage 12-24V with a current of at least 4A
The board is equipped with a radiator.
This TPA3116D2 amplifier can be recommended for:
- amateur radio designs with high output sound signal power (including self-powered);
- a laboratory amplifier for tuning and repairing sound reproducing equipment;
- alterations of passive speakers into active ones.
