Descriptions

The DIO2140 is a 2.8 W high-efficiency filter-free

Class-D audio amplifier, which needs only three

external components. Its optimized PWM output

stage eliminates the LC output filter.

The DIO2140 features its filter-free Class-D

architecture, which leads to a reduction of

peripheral components amount, PCB board area,

and system cost. And high efficiency of up to

90% makes it suitable for cell phones and other

mobile device applications.

Moreover, the DIO2140 is also equipped with

protection functions, such as a short circuit

protection function for the speaker output

terminal, thermal shutdown function for inside of

the device, and under voltage lockout.
