NCP4896

www.DataSheet4U.com NCP4896 1.0 Watt Audio Power Amplifier with Earpiece Driving Capability The NCP4896 is an audio power amplifier designed for portable communication device applications such as mobile phones. This part is capable of delivering 1.0 W of continuous average power to an 8.0 W BTL load from a 5.0 V power supply and, 250 mW to a 4.0 W BTL from 2.6 V power supply. It also provides the control of driving a single−ended earpiece and delivers 90 mW from a 5.0 V power supply to a 32 W load. This device provides high quality audio while requiring few external components and minimal power consumption. It features a low−power consumption shutdown mode, which is achieved by driving the shutdown pin with logic Low. The NCP4896 contains circuitry to prevent from “pop and click” noise that would otherwise occur during turn−on and turn−off transitions. It is also efficient when switching modes from BTL to SE and SE to BTL. For maximum flexibility, the part provides an externally controlled gain (with resistors), as well as an externally controlled turn−on time (with bypass capacitor). Due to its excellent PSRR, it can be directly connected to the battery, saving the use of an LDO.
