LM4890

1 Watt Audio Power Amplifier

National Semiconductor

LM4890 Features

* a low-power consumption shutdown mode, which is achieved by driving the shutdown pin with logic low. Additionally, the LM4890 features an internal thermal shutdown protection mechanism. The LM4890 contains advanced pop & click circuitry which eliminates noises which would otherwise occur during turn

LM4890 General Description

The LM4890 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 8Ω BTL load with less than 1% distortion (THD+N) from a 5VDC power supply. .
