• 8W per channel (THD+N=10%)output power into
8Ω load at 12V, Class D output
• MONO function combines two channels’output to
supply 12W into a 4Ω load at 12V (THD+N=10%)
• Adjustable Power limit function plus DC Protec-
tion
• Thermal and Over-Current Protections with Auto-
Recovery option
• TSSOP-28P with thermal pad packages
• QFN4x4-28 with thermal pad packages
Applications
The APA2613A is a stereo, high efficiency, Class-D audio
amplifier available in TSSOP-28Pand QFN4x4-28A pins
packages.
The Class-D power amplifier has higher efficiency com-
pare to the tradition Class-AB power amplifier. The filter-
free Class-D architecture eliminates the external low pass
filters. The internal gain setting can minimum the exter-
nal component counts, and for the flexible application the
gain can be set to 4-step 20, 26, 32, 36dB by gain control
ins (GAIN0 and GAIN1). The power limit function cans
protection the speaker when output signal excess the
speaker limit rating.
The integration of Class-D power amplifier is a best so-
lution for power efficiency and lower the total BOM costs.
The operating voltage is from 8V to 26V. The APA2613A
power amplifiers are capable of driving 6 W at V =10V
DD
into 8Ω speaker, and provides thermal and over-current
protections also can detection the DC that prevent to de-
stroy the speaker voice coil.
