Print

General Descriptions :

The AP1088 is a differential input and differential output mono headphone amplifier. It is capable of delivering 40mW average power into 8Ω BTL loads with 0.08% THD+N. The device operates from 2.5V to 5V.

The active noise cancellation is designed to reduce the far-field ambient noise from the headphones. Up to 25dB of far-field ambient noise can be reduced with a properly configured and +/-0.5dB matched microphones.

The AP1088 consumes only 1.8mA of supply current during operation. It provides superior power saving over DSP solutions which typically consume five times more power.
