APA4880 Stereo 330mW 8Ω Speak Driver With Mute Features • Operating Voltage Single Supply Dual Supply 3V to 7V ±1.5V to ± 3.5V Applications • • • • • Portable Digital Audio Personal Computers Microphone Preamplifier CD ROM Player Headphone Amplifier • • • • • Depop Circuitry Integrated. High Signal-to-Noise Ratio High Slew Rate Low Distortion Output Power at 10% THD+N into 8 Ω into 16 Ω 3 30mW 2 00mW 100dB 5.5V/ms -66dB 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). • • • • • • • Large Output Voltage Swing Excellent Power Supply Ripple Rejection Low Power Consumption Short-circuit Elimination Wide Temperature Range No Switch ON/OFF Clicks Available in 8 pin SOP,TSSOP or PDIP Package Ordering and Marking Information APA4880 L e a d F re e C o d e H a n d lin g C o d e Tem p.
