TDA8954TH Audio Amplifier: Datasheet, Pinout, Circuit [Video&FAQ]

Product Overview

The TDA8954 is a stereo or mono high-efficiency Class D audio power amplifier in a single IC featuring low power dissipation. It is designed to deliver up to 2 × 210 W into a 4 Ω load in a stereo Single-Ended (SE) application, or 1 × 420 W into an 8 Ω load in a mono Bridge-Tied Load (BTL) application.

 

It combines the benefits of Class D efficiency (≈93 % into a 4 Ω load) with audiophile sound quality comparable to that associated with Class AB amplification.

 

This blog will introduce TDA8954TH systematically from its features, pinout to its specifications, applications, also including LM3900 datasheet and so much more.

TDA8954TH FAQ

What does an audio amplifier do?

The goal of audio amplifiers is to reproduce input audio signals at sound-producing output elements, with desired volume and power levels—faithfully, efficiently, and at low distortion.

 

What are the 3 types of amplifiers?

There are three different kinds of amplifier gain which can be measured and these are: Voltage Gain ( Av ), Current Gain ( Ai ) and Power Gain ( Ap ) depending upon the quantity being measured with examples of these different types of gains are given below.

 

What is the difference between audio and power amplifier?

A transistor which is suitable for power amplification is known as a power transistor. It differs from other transistors mostly in size. It is normally larger for handling the large amount of power it delivers. Audio power amplifiers are used to deliver a large amount of power to a low resistance load.
