ON Semiconductor has introduced a new Class D audio amplifier with an integrated charge pump that provides a space-efficient speaker amplifier solution for applications such as cellphones, digital video recorders and portable speakers.
The NCP2830 is a 1 W constant power filterless device that delivers continuous audio output to an 8 Ω bridge tied load (BTL) with less than 1% total harmonic distortion - even if the input voltage varies. This results in longer equipment operating times as the user does not experience reduced audio volume or distortion as the battery depletes. Housed in a 20-pin QFN package measuring just 3 x 3 x 0,5 mm, the device occupies minimal board space and can also be used where component height is restricted.
The amplifier operates from a supply voltage of between 2,7 V and 5,5 V, has a fast start-up time of 200 μS and a power supply ripple rejection ratio (PSRR) of
-88 dB. Overall efficiency is up to 89% and low noise performance is underlined by a signal-to-noise ratio (SNR) of 100 dB. A pulse width modulation (PWM) output stage gives the NCP2830 filterless capability that further reduces the number of external components required.
