1 / 16 page Key Features Applications 3W Output at 10% THD with a 4 Load and 5V Power Supply Filterless, Low Quiescent Current and Low EMI Low THD+N 64-step DC Volume Control Headphone Output Function Superior Low Noise Low pop noise Efficiency up to 92% Short Circuit Protection Thermal Shutdown Few External Components to Save the Space and Cost LCD Monitors / TV Projectors Notebook Computers Portable Speakers Portable DVD Players, Game Machines VoIP/Speaker Phones directly It can extend the battery life thus be ideal for portable ap plications. Ω n n n n n General Description The PAM8007 is a 3W, class-D audio amplifier with headphone amplifier. Advanced 64-step DC volume control minimizes external components a n d a l l o w s s p e a k e r v o l u m e c o n t r o l a n d headphone volume control. It offers low THD+N, to produce high-quality sound reproduction. The new filterless architecture allows the device to drive the speaker , without low-pass output filters which will save 30% system cost and 75% PCB area. With the same numbers of external components, the efficiency of the PAM8007 is muc h better than class-AB cousins. The PAM8007 is available in a SSOP-24 and SOP- 24 package. , n n n n n n n n n n n n Pb-Free Package PAM8007 Filterless 3W Class-D Stereo Audio Amplifier with DC Volume Control and Headphone Output 1 www.poweranalog.com Typical Application , Power Analog Microelectronics Inc MUTE 6 5 EarInL 15 EarInR Line/ Ear H: Headphone L: Class D (de fault) EarOutL EarOutR - -OUTR +OUTR 21 24 VDC - -OUTL +OUTL VDD 1 4 VREF 11 DC Volume 14 10 7 17 16 PVDDL PGN DL PGN DL 3 Headphone 13 12 2 PVDDR 0.47 F μ INL 8 PGNDR PGN DR INR GND 9 INL PAM8007 INR 20 18 SHDN MUTE VDD V OLUME 23 19 SHDN ON 22 ON PVDDL 0.47 F μ 0.47 F μ 0.47 F μ 1 F μ 1 F μ 1 F μ 10 F μ 1 F μ 10 F μ + - + - 220 F μ 220 F μ 01/2012 Rev1.2 |
