CLASS AB/D OPTIONAL

SECOND GENERATION

CLASS-D AUDIO AMPLIFIER



DESCRIPTION

The UTC UPA8155 is a second-generation Class D audio

amplifier with crack-free noise (NCN), ultra-low THD+N, no filter,

AB/D output mode selection for the most comfortable listening

experience for customers.

SOP-8

The UTC UPA8155 NCN output power can be set for different

speakers, this feature is to protect the speaker from damage

caused by excessive sound levels.

The filter-less PWM architecture and internal gain Settings

reduce the number of external components, board area

consumption, system costs, and simplify design. Overcurrent and

over-temperature are prepared inside the device.



* Low Shutdown Current (<0.1µA)

* AB/D Operate Mode

* Excellent Pop-Click Suppression

* One-Pulse Control

* Over-Current Protection

* Two NCN Level: 0.65W and 0.85W

* Ultra Low THD+N: 0.06%

* Filter-Free Class-D Architecture

* High PSRR (-70dB at 217Hz)

* Over-Temperature Protection
