DIO2140

2.8 W, Monaural Filter-Free, Class-D Audio Amplifier

Features

Descriptions



Maximum output: > 2.5 W, output under 4 Ω

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.

load



Distortion rate (THD):

0.05% (V_DD= 5.0 V, P_O= 1 W)

High efficiency up to 83% at 400 mW

Filter-free Class-D architecture

Needs only three external components

Short circuit protection function

Thermal shutdown function

Under voltage lockout function

Green package: DFN-8 and MSOP-8



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.
