The LM4902MM is a mono Class AB audio amplifier optimized for low-power portable applications. Operating from 2V to 5.5V, it delivers 675mW into an 8Ω load. Its small 8-VSSOP package and wide temperature range make it suitable for space-constrained designs. Ideal for battery-powered devices such as radios, intercoms, and alarms.
- Low Voltage Operation: Works from 2V, compatible with single-cell batteries.
- Compact Package: 8-VSSOP saves space in portable designs.
- Sufficient Output: 675mW into 8Ω for clear audio in small speakers.
- Wide Temperature Range: -40°C to 85°C for reliable operation in harsh environments.
Portable Bluetooth Speaker
The LM4902MM provides 675mW into 8Ω, sufficient for small Bluetooth speakers, and its 2V minimum supply allows direct operation from a single AA battery.
AM/FM Radio
Its low noise and differential input capability make it suitable for amplifying audio in portable AM/FM radios with minimal distortion.
Intercom System
The compact 8-VSSOP package and wide temperature range make the LM4902MM ideal for intercoms used in industrial or outdoor environments.
Alarm Driver
With 675mW output, it can drive small alarm speakers, and the shutdown feature reduces power consumption when not in use.
DIY Audio Projects
Hobbyists can easily integrate this amplifier into custom audio projects due to its simple pinout and low external component count.
