Gereral Description

The APA4880 is an integrated class AB stereo head­phone amplifier contained in an SO-8 or a DIP-8 plas­tic package. The APA4880 is capable of delivering
330mW of max. output power to an 8Ω load with less
than 10% (THD+N) from a 5V power supply. The
device has been primarily developed for portable digi­tal audio applications. Both of the depop circuitry and
mute circuitry are integrated in the APA4880 , that
reduces pops and clicks noise during power up and
when using the mute mode(high active).

• No Switch ON/OFF Clicks

• Available in 8 pin SOP,TSSOP or PDIP
