ChipSourceTek NS4890B

The NS4890 is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications. It is capable of delivering 1.6 watts of continuous average power to a 4Ω BTL load with less than 1% distortion (THD+N) from a 5VDC power supply. The NS4890 does not require output coupling capacitors, therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement.

DESCRIPTION

The NS4890 features a low-power consumption shutdown mode. To facilitate this, Shutdown may be enabled by either logic high or low depending on mode selection. The NS4890 contains advanced pop & click circuitry which eliminates noise which would otherwise occur during turn-on and turn-off transitions. The NS4890 is unity-gain stable and can be configured by external gain-setting resistors.
