NOCAPt Advanced Stereo

Headphone Amplifier

NCP2811 is a dual audio power amplifier designed for portable

communication device applications such as mobile phones. This part

is capable of delivering 27 mW of continuous average power into a

16 Ω load from a 2.7 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. In this True Ground configuration, the two

external heavy coupling capacitors can be removed. It offers

significant space and cost savings compared to a typical stereo

application.

NCP2811 is available with an external adjustable gain (version A),

or with an 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 from “Pop & Click” noise that would otherwise occur

during turn−on and turn−off transitions. The device is available in 12

bump CSP package (2 x 1.5 mm) which help to save space on the

board. It is also available in WQFN12 and TSSOP−14 packages.
