General Description
The LM4901 is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications.
Key Features
- a low-power consumption shutdown mode. To facilitate this, Shutdown may be enabled by either logic high or low depending on mode selection. Driving the shutdown mode pin either high or low enables the shutdown pin to be driven in a likewise manner to enable shutdown. The LM4901 contains advanced pop & click circuitry which eliminates noise which would otherwise occur during turn-on and turn-off transitions. The LM4901 is unity-gain stable and can be configured by external gain-setting resistors.
