The LM4889 is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications. It is capable of delivering 1 watt of continuous average power to an 8 BTL load with less than 2% distortion (THD+N) from a 5VDC power supply.
Boomer audio power amplifiers were 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 contains advanced pop & click circuitry to eliminate noise which would otherwise occur during turn-on and turn-off transitions.
The LM4889 is unity-gain stable and can be configured by external gain-setting resistors.
