Audio Power Amplifiers | NCP2815
概览
NCP2815 is a dual LongPlay true ground headphone amplifier designed for portable communication device applications such as mobile phones. This part is capable of delivering 26 mW of continuous average power into a 32 Ω load from a 1.8 V power supply with a THD+N of 1%. Based on the power supply delivered to the device, an internal power management block generates a symmetrical positive and negative voltage. Thus, the internal amplifiers provide outputs referenced to Ground and the losses are reduced which helps to increase the battery life. In this NOCAPTM configuration, the two external heavy coupling capacitors can be removed. It offers significant space and cost savings compared to a typical stereo application. NCP2815 is available with an external adjustable gain (version A), or with an internal gain (version B). It reaches a superior PSRR and noise floor. Thus, it offers high fidelity audio sound, as well as a direct connection to the battery. It contains circuitry to prevent from Pop and Click noise that would otherwise occur during turn on and turn off transitions. The device is available in 12 bump CSP package (1.2 x 1.6 mm) which help to save space on the board.
