WebFor an audio amplifier with 10-W PLOAD max, an average PLOAD of 1 W can be considered a realistic listening level. Under this condition, 282 mW is dissipated inside the Class D output stage, vs. 2.53 W for Class B and 30.2 W for Class A. In this case, the Class D efficiency is reduced to 78%—from 90% at higher power. WebAdditionally, with the TIA amplifier, the PER increases rapidly when the devices are placed in different rooms. Comparing the BJT and TIA amplifiers, it can be seen that the amplifier circuitry is very sensitive to vertical and horizontal distances. In ideal positions, both amplifiers provide a similar PER between WuRx of about 0%.
