Overview

NCP4894 1.8 Watt Differential Audio Power Amplifier with Selectable Shutdown The NCP4894 is a differential audio power amplifier designed for portable communication device applications.

This feature and the excellent audio characteristics of the NCP4894 are a guarantee of a high quality sound, for example, in mobile phones applications.

With a 10% THD+N value the NCP4894 is capable of delivering 1.8 W of continuous average power to an 8.0 W load from a 5.5 V power supply.

Key Features

  • a low.
  • power consumption shutdown mode. To be flexible, shutdown may be enabled by either a logic high or low depending on the voltage applied on the SD MODE pin. The NCP4894 contains circuitry to prevent from “pop and click” noise that would otherwise occur during turn.
  • on and turn.
  • off transitions. For maximum flexibility, the NCP4894 provides an externally controlled gain (with resistors), as well as an externally controlled turn.
  • on time (with bypass capacitor). D.
