IS31AP4913
3D AND BASS ENHANCEMENT STEREO HEADPHONE DRIVER
December 2013
GENERAL DESCRIPTION
The IS31AP4913 is a stereo headphone driver
designed to allow the removal of the output
DC-blocking capacitors for reduced component count
and cost. The IS31AP4913 is ideal for small portable
electronics where size and cost are in concerns.
The IS31AP4913 also features 3D and bass
enhancement which can be externally adjusted by a
simple RC network.
IS31AP4913 is available in QFN-20 (3mm × 3mm)
packages. It operates from 2.7V to 5.5V over the
temperature range of -40°C to +85°C.
FEATURES
No output DC-blocking capacitors
Bass enhancement
3D enhancement
Low output noise (8µV)
High SNR (102dB)
-92dB PSRR
Pulse Count Control serial interface
Thermal protection circuit
Integrated click-and-pop suppression circuitry
QFN-20 (3mm × 3mm) package
APPLICATIONS
Cellular handsets and PDAs
Notebook PC
MP3
Portable gaming
TYPICAL APPLICATION CIRCUIT
Figure 1 Typical Application Circuit
Note: The SGND and PGND pins of the IS31AP4913 must be routed separately back to the decoupling capacitor in order to provide proper
device operation. If the SGND and PGND pins are connected directly to each other, the part will function without the risk of failure, but the noise
and THD performance do not meet the specifications.
