NCP2990FCT2GEVB:NCP2990FCT2G 1.3 W Audio Amplifier Evaluation Board
The NCP2990 is an audio power amplifier designed for portable communication device applications such as mobile phone applications. The NCP2990 is capable of delivering 1.3 W of continuous average power to an 8.0 Ω load from a 5.0 V power supply, and 1 W to a 4.0 Ω load from a 3.6 V power supply. The NCP2990 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. In case of a single ended input, the NCP2990 contains circuitry to prevent from 'pop and click' noise that would otherwise occur during turn-on and turn-off transitions. For maximum flexibility, the NCP2990 provides an externally controlled gain (with resistors), as well as an externally controlled turn-on time (with the bypass capacitor). When using a 1 uF bypass capacitor, it offers 60ms wake up time. Due to its excellent PSRR, it can be directly connected to the battery, saving the use of an LDO.
