• 32-Step DC Volume Control With Hysteresis
• 9W Per Channel Output Power into 8Ω Load at
12V, Class-D Output
• 12W Per Channel Output into 6Ω Load at 12V,
Class-D Output
• 5V LDO Output for Powering APA4801 Head-
phone Driver
• Line Output for APA4801 Headphone Driver with
DC Volume Control
• Low Current Consumption in Shutdown Mode
(10µA, Typical)
• APA3002 will Auto-Recovery after Over-Current
Protection
• Thermal and Over-Current Protections
• TQFN7x7-48 with Thermal Pad Package
TQFP7x7-48P with Thermal Pad Package
• Lead Free and Green Devices Available
(RoHS Compliant)
The APA3002 is a monolithic integrated circuit, which pro-
vides precise DC volume control, and a stereo Class-D
audio power amplifiers capable of producing 9W into 8Ω
(12V) with less than 10% THD+N. The attenuator range
of the volume control in the APA3002 is from 36dB
(V =5V) to -40dB (V =0V) with 32 steps. The ad-
VOLUME
VOLUME
vantage of internal gain setting can be less components
and PCB area. The circuitries of both thermal and the
over-current protections are integrated in the APA3002. It
protects the chip from being destroyed by over tempera-
ture and over current failure.
To simplify the audio system design, the APA3002 com-
bines a line output for external headphone driver with
volume control and a 5V regulator for external headphone
drive, where the speaker output can be switched off by
the headphone jack’s switch pin that connects to the
APA3002’s mode pin as shown in the application circuit.

Note : ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and
advise customers to obtain the latest version of relevant information to verify before placing orders.
