Product Overview
The LM4889MA is an Audio Power Amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications. It is capable of delivering 1W of continuous average power to an 8R BTL load with less than 2% distortion (THD+N) from a 5VDC power supply. Boomer™ audio power amplifier was designed specifically to provide high quality output power with a minimal amount of external components. The LM4889 does not require output coupling capacitors or bootstrap capacitors and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement. The LM4889 features a low-power consumption shutdown mode, which is achieved by driving the shutdown pin with a logic low. Additionally, the LM4889 features an internal thermal shutdown protection mechanism. The LM4889 is unity-gain stable and can be configured by external gain-setting resistors.
- Ultralow current shutdown mode
- Can drive capacitive loads up to 500pF
- Improved pop and click circuitry eliminates noises during turn-on and turn-off transitions
- No output coupling capacitors, snubber networks or bootstrap capacitors required
- Unity-gain stable
- External gain configuration capability
- Green product and no Sb/Br
Applications
Audio, Consumer Electronics, Portable Devices, Communications & Networking
