The DIODES Advantage

The PAMS58xx family consists of fully integrated, high-

efficiency, stereo Class-D audio amplifiers with digital inputs.

The PAMS58xx family consists of fully

integrated, high-efficiency, stereo Class-D

audio amplifiers with digital inputs. The

PAMS58xx family includes five members:

PAMS5803, PAMS5804, PAMS5825,

PAMS5826, and PAMS5827, each offering

a wealth of features. All devices have the

same pin sequence definition and can share

the same PCB layout design, only the

maximum output power and audio tuning

differ.

This family supports PVDD with an

operation range of 4.5V to 16–26.4V, while

DVDD supports either 3.3V or 1.8V. With

the integration of a few passive

components, these devices deliver stereo

output powers ranging from 24W to 41W per

channel, or mono output power between

40W and 82W, at 1% total harmonic

distortion plus noise (THD+N).

The PAMS58xx devices have enhanced

audio performance features, such as a

noise value lower than 37µVRMS, THD+N

down to 0.02%, and efficiency over 90%.

The PAMS58xx supports Class-H and SSM

functions. The advanced audio-tuning

provides DRC/EQ/DRB for audio designs.

The PAMS58xx is available in the thermally

enhanced TSSOP-28EP package.
