Features like 89% efficiency, -63dB PSRR, improved RF-rectification immunity, and very small PCB area make the class-D amplifier ideal for cellular handset and PDA applications. In cellular handsets, the earpiece, speaker phone, and melody ringer can each be driven by the . The allows independent gain by summing signals from seperate sources, and has as low as 43 V noise floor. PAM8404 is available in QFN 4mmx4mm packages. μ n n n n n n Pb-Free Packages Typical Application Circuit 1 www.poweranalog.com , Power Analog Microelectronics Inc PAM8404 3W/CH Filterless Stereo Class-D Audio Amplifier 03/2009 Rev 1.1 FCC Class B Limit Radiated Emissions AGND SDL SDR INL- INL+ INR- INR+ G0 G1 AVDD PVDD PGND PAM8404 OUTL- OUTL+ OUTR- OUTR+ 0.22μF 0.22μF 0.22μF 0.22μF INR+ INR- INL+ INL- OFF ON ON OFF 10μF 1μF VDD 1μF 10μF G1 G0 VDD |
