The APA4880 is an integrated AB class 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 digi- tal 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).
The ANPEC APA4880 is an integrated class AB stereo headphone amplifier designed primarily for portable digital audio applications. It delivers up to 330mW of output power into an 8Ω load with less than 10% THD+N from a 5V supply. The device features integrated depop and mute circuitry to reduce noise during power-up and when using the mute mode.
