With the input voltage shown (roughly ±35V peak) and a more-or-less standard input 'protection' circuit, it takes less than 3 cycles (3ms) to 'pump' the supply rails up to over ±30V, even with a total nominal load of 15mA on each supply (rising to 30mA).

Simple audio peak limiter circuit diagram But now the output may be a square wave. We need just the sine wave that is a higher volume on a loudspeaker. It may make oscillated, too. Which the power amplifier and loudspeaker are damaged. Thus, this circuit will protect the input of power amplifier away high amplitude, more than 1Vrms.

Circuit Examples Solution 1 To protect a standard audio port (e.g.. RCA-type jack) used in Audio/Video equipment, a single-channel protection device is recommended. A high capacitance 0402 or 0603- size multilayer varis-tor (MLV) will provide the IC with protection against ESD transients as well as providing EMI filtering to eliminate noise from the circuit.

The series R in the RC filter between the amplifier and the ADC input can also be used to limit the current seen at the ADC input during an overvoltage condition. However, this will be a trade-off between current limiting and ADC performance. Larger series R will give better input protection but result in greater distortion in the ADC performance.

To get around this, you can create an analog input protection circuit to allow you to make measurements on higher voltages, while minimizing the risk of frying your pin or whole board. Here I will go over the design method I used to create a voltage divider and diode clamp to protect an analog input pin on a uC32 microcontroller, but these concepts can be applied to creating a …

The simplest protection mechanism is a current limiting resistor, as shown in Figure 6. The input resistor is sized so that the voltage drop across it does not affect the voltage at the microcontroller input. As this is a simple voltage divider, and the input resistance in the controller is about 20 MΩ, this resistor can be fairly big.

Overvoltage Protection. A “crowbar” circuit (shown in Figure 1) can protect your device from overvoltage. In normal use, the 12V supply goes to the output via the reverse protection diode and fuse. The Zener diode is chosen to be slightly higher; in this case, 15V. When the input voltage reaches 15V, the Zener conducts, setting up a voltage across R2.

This circuit enables the full galvanic isolation of sound frequency signals with optical transmission in excellent quality, eliminating interference. When you connect audio components, interference may occur from various power and signal grounds. For safety reasons, screenings are interconnected through the protection ground and the protection wire.
