LM3886TF Typical application Circuitry

LM3886TF

The LM3886TF is a high-performance audio power amplifier that can output 38W into an 8 Ohm load and 68W of average continuous power into a 4 Ohm load with 0.1% THD+N from 20Hz to 20kHz. It is a piece of the Overture series from Texas Instruments. In order to interface this amplifier with your circuitry, let's take a look at some of its critical pins:

1. Power Supply Pins (V+, V-, Pins 1 and 4): Pin 1 (V+) is the positive power supply input and should be connected to a positive voltage, typically +35V. The negative voltage, generally -35V, should be connected to pin 4 (V-), which is the negative power supply input.

2. Signal Ground (SG, Pin 7): This pin acts as the signal reference ground. It has to be linked to the ground of the source of your signal input.

3. Mute (Mute, Pin 8): The Mute pin controls the mute function. A voltage applied to this pin can turn off the output, providing a muting function. The use of this pin relies on the particular specifications of your design.

4. Input (In, Pin 10): The Input pin is where the audio signal to be amplified is input. Connect this pin to your audio source.

5. Output (Out, Pin 3): This pin is the output of the amplifier. Connect your speaker or other output device to this pin.

6. Bootstrap (Boot, Pin 5): The Bootstrap pin is connected to an external capacitor used to improve performance.

7. Feedback (Pin 9): Connect this pin to the output through a resistor to create a feedback loop.

Remember, the LM3886TF operates in a single-supply or split-supply manner. The power source's capacity to deliver the required output power is a requirement. Always follow the data sheet guidelines, consider decoupling capacitors near power pins, and use appropriate grounding to reduce noise and oscillations. Also, note the proper heat sinking requirements of the LM3886TF, as it can run quite warm when driving high-power loads.
