LM4890 Product details

Description

The LM4890 is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications.

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-on and turn-off transitions. The LM4890 is unity-gain stable and can be configured by external gain-setting resistors. Key Specifications j PSRR at 217Hz, VDD = 5V (Fig. 1) j Power Output at 5.0V &.
