NCP2815

NOCAPt LongPlay

Headphone Amplifier

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 W 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 NOCAP configuration, the two

external heavy coupling capacitors can be removed. This provides a

significant space and cost savings compared to a typical stereo

application.

NCP2815 is available with an external adjustable gain (version A),

or internal gain of −1.5 V/V (version B). It reaches a superior −100 dB

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

“Pop & 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 helps to save space on the board.
