LM4950TS/NOPB Typical application Circuitry

LM4950TS NOPB

LM4950TS/NOPB is a 7.5W audio power amplifier designed for portable and compact applications where space and power efficiency are critical. It is particularly suited for devices such as portable speakers, laptops, and other personal audio playback devices.

Application Scenarios

One practical application for the LM4950TS/NOPB is in the design of a compact portable speaker system, where it can drive a small to medium-sized speaker with high efficiency and minimal external components.

Parameter Features

- High Output Power: The LM4950TS/NOPB can deliver up to 7.5W of power into an 8Ω load with a 5V power supply, providing ample volume for personal audio applications.

- Wide Supply Voltage Range: It operates across a broad supply voltage range, accommodating various battery technologies and configurations.

- No Bootstrap Capacitors Needed: This feature minimizes the number of components and board area while streamlining the circuit design.

- Thermal Shutdown Protection: Includes built-in thermal shutdown protection, enhancing the reliability of the device in operation.

Circuit Connection Example: Compact Portable Speaker

Integrating the LM4950TS/NOPB into a compact portable speaker involves several key steps:

- Power Supply Connection: Connect a 5V DC power supply to the VDD pin (pin 8) of the LM4950TS/NOPB. This voltage level is perfect for portable applications because it is frequently seen in USB-powered devices.

- Input Signal: The audio input should be fed into the IN+ pin (pin 6) for mono output. If stereo to mono conversion is needed, a simple resistor network can combine the left and right channels before connecting to the IN+ pin.

- Speaker Output: Connect the speaker between the OUT+ pin (pin 9) and the OUT- pin (pin 10). This differential output configuration helps to maximize the output power efficiency and reduce electromagnetic interference.

- Shutdown Control: The SHUTDOWN pin (pin 3) allows the amplifier to be turned off to conserve power when not in use. This pin can be connected to a switch or controlled by a microcontroller for automated power management.

Design Considerations

When designing with the LM4950TS/NOPB, it's crucial to ensure proper heat dissipation, especially when operating at higher output powers or in enclosed spaces. Additionally, the layout should minimize the length of the signal paths between the audio source, the LM4950TS/NOPB, and the speaker to reduce potential noise and distortion. Care should also be taken to separate audio signal paths from power supply lines to avoid interference.

In summary, the LM4950TS/NOPB offers a high-performance, compact solution for audio amplification in portable devices. By carefully considering power management, thermal design, and signal integrity, designers can effectively utilize the LM4950TS/NOPB to create high-quality audio applications with minimal complexity and cost.
