This application report explains the different types of audio power amplifier configurations, such as the single-ended (SE), the bridge-tied load (BTL) and the fully differential audio amplifier.

This application note provides guidelines for measuring the data sheet parameters of Texas Instruments audio power amplifiers (APAs) using prefabricated evaluation modules (EVMs).

The circuit works by simply requiring a certain positive supply rail voltage before the LED turns on and the amplifier switches out of Mute mode. The DZ1 Zener diode begins to conduct once the …

Achieving high CMRR in line-receiver circuitry for balanced audio applications requires careful circuit design, component selection and PCB layout. By examining the CMRR of a circuit …

Uses include simple phonograph amplifiers, intercoms, line drivers, teaching machine outputs, alarms, ultrasonic drivers, TV sound systems, AM-FM radio, small servo drivers, power …
