15W Stereo Class-D Audio Power Amplifier
Features
General Description
• Supply Voltage is 8V ~ 26V
• Class D operation eliminates heat sink & reduce
power supply requirement
• 20,26, 32, 36, 4 steps gain setting
• 15W/ch into an 8Ω Loads at 10% THD+N from a 16-
V supply
• 10W/ch into 8Ω Loads at 10% THD+N from a 13V
supply
• 30W into a 4Ω Mono Load at 10% THD+N from a
16V Supply
• 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 APA2614 is a stereo, high efficiency, Class-D audio
amplifier available in TSSOP-28Pand QFN4x4-28 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 APA2614
power amplifiers are capable of driving 15 W at V =16V
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.
