FAQs
What is LM4870?
The LM4870 is a mono, bridged audio power amplifier designed by Texas Instruments. It is ideal for driving a single speaker with higher output power, making it suitable for portable electronics, laptops, and small audio systems.
How Does LM4870 Work?
The LM4870 works by amplifying audio signals to drive a speaker with sufficient power. It operates in a bridged configuration, allowing it to deliver higher output power compared to a single-ended amplifier. The amplifier is designed for low voltage operation, making it suitable for battery-powered devices.
How Many Pins does LM4870 have and What are the Functions of the Pinout Configuration?
The LM4870 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:
- VDD, VSS: Power supply pins.
- SD: Shutdown pin for power management.
- IN-: Inverting input pin.
- IN+: Non-inverting input pin.
- OUT1, OUT2: Bridge output pins.
What are the Pros and Cons of LM4870?
Pros:
- Bridged Configuration: Provides higher output power due to the bridged amplifier design.
- Low Voltage Operation: Suitable for battery-powered devices and portable electronics.
- Compact Package: Housed in an 8-pin SOIC package for space-efficient designs.
- Thermal Shutdown Protection: Includes built-in thermal shutdown protection for enhanced reliability.
Cons:
- Single-Channel Output: Designed for driving a single speaker, limiting its application in stereo systems.
- Power Dissipation: May generate more heat due to the higher output power capability.
- External Components: Requires external coupling capacitors for proper operation.
Are There Any Equivalents/Alternatives to LM4870 for Recommendation?
- The TPA2030D1 from Texas Instruments is a similar mono audio power amplifier with low voltage operation.
- Alternatives to the LM4870 include the NJM2801 from New Japan Radio and the TDA7267 from STMicroelectronics.
