NCP9002

NCP9002 1.3 Watt Audio Power Amplifier with Fast Turn On Time The NCP9002 is an audio power amplifier designed for portable communication device applications such as mobile phone applications. The NCP9002 is capable of delivering 1.3 W of continuous average power to an 8.0 W BTL load from a 5.0 V power supply, and 1.0 W to a 4.0 W BTL load from a 3.6 V power supply. The NCP9002 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 NCP9002 contains circuitry to prevent from “pop and click” noise that would otherwise occur during turn−on and turn−off transitions. For maximum flexibility, the NCP9002 provides an externally controlled gain (with resistors), as well as an externally controlled turn−on time (with the bypass capacitor). When using a 1 mF bypass capacitor, it offers 100 ms wake up time. Due to its excellent PSRR, it can be directly connected to the battery, saving the use of an LDO. This device is available in a 9−Pin Flip−Chip CSP (Lead−Free).
