NCP2811  
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.
