WebProduct information "UcD700HG with HxR". The UcD700HG amplifier module is a self-contained high-performance class D amplifier intended for a wide range of audio applications, ranging from Public Address systems to ultrahigh-fidelity replay systems for studio and home use. Chief distinguishing features are flat frequency response … The lower power dissipation provides a strong motivation to use Class D for audio applications, but there are important challenges for the designer. These include: 1. Choice of output transistor size 2. Output-stage protection 3. Sound quality 4. Modulation technique 5. EMI 6. LC filter design 7. System cost See more 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. Audio frequencies range … See more In a conventional transistor amplifier, the output stage contains transistors that supply the instantaneous continuous output current. The many possible implementations for audio systems include Classes A, AB, … See more Figure 3 shows a differential implementation of the output transistors and LC filter in a Class D amplifier. This H-bridge has two half-bridge switching circuits that supply … See more Linear-amplifier output stages are directly connected to the speaker (in some cases via capacitors). If bipolar junction transistors (BJTs) are used in the output stage, they generally … See more how to organize qualitative data research
