Power booster

The power booster is designed to drive moderate loads. The circuit utilizes a NE5535 device. Other amplifiers may be substituted, provided that the resistor values (R1) are adjusted according to the Icc current requirements of the chosen amplifier. Additionally, R1 should be calculated using the following expression.

The power booster circuit primarily employs the NE5535 operational amplifier, which is known for its high performance in terms of bandwidth and low distortion. This device is well-suited for applications where moderate load driving capability is essential. The NE5535 features a dual operation, allowing for flexibility in design configurations.

When substituting the NE5535 with alternative amplifiers, it is crucial to consider the supply current (Icc) specifications of the new amplifier. Each amplifier may have different current requirements, which will impact the resistor values in the circuit. Specifically, R1 must be recalculated to ensure that the circuit operates within the desired parameters and maintains stability.

To determine the value of R1, the following expression should be used:

\[ R1 = \frac{V_{supply} - V_{out}}{I_{cc}} \]

Where:
- \( V_{supply} \) is the supply voltage provided to the circuit.
- \( V_{out} \) is the output voltage level required for the load.
- \( I_{cc} \) is the supply current needed by the amplifier being used.

This formula allows for precise tuning of the resistor to accommodate the specific operational characteristics of the selected amplifier, ensuring optimal performance of the power booster circuit. Additionally, careful attention should be paid to the power ratings of all components to prevent overheating and ensure reliability during operation.Power booster is capable of driving moderate loads. The circuit as shown uses a NE5535 device. Other amplifiers may be substituted only if R-l values are changed because of the Icc current required by the amplifier R1 should be calculated from the following expression:.
