Press Release Summary:
Featuring EMI under 30 dBuV/m for frequencies up to 700 MHz, stereo Model PAM8403 and mono Model PAM8303S provide efficiency higher than 90% with 8 W load. Only one input coupling capacitor per channel is needed in external circuit. Housed in 24-pin SOP and SOP-8 packages respectively, 3 W units are suited for digital photo frames, MP4/PMP, GPS navigators, PC speakers, portable DVD players, LCD monitors, and cell phones.

Power Analog Microelectronics Introduces Industry's Best EMI 3W Class-D Audio Amplifier Family
SANTA CLARA, Calif., and TAIPEI, Taiwan, June 7 /-- Power Analog Microelectronics (PAM), a developer of innovative Class-D digital audio amplifiers and high-power LED display driver semiconductors, today announced the expanded product offerings of its proprietary 3W Class-D audio amplifiers from its patent pending "filter-free," next generation architecture. This introduction of the PAM8x03 family was made to coincide with the Computex Electronics Show, being held this week in Taipei, Taiwan.
The PAM8403 stereo and PAM8303S mono 3W audio amplifiers are the latest addition to PAM's family of products. They employ a unique filter-free architecture that has inherently lower EMI than competing products. In fact, not only do the parts pass the FCC Class B standard, but the EMI is under 30dBuV/m for frequencies up to 700MHz. Its efficiency is higher than 90% with an 8-ohm load. Only one input coupling capacitor per channel is needed in the external circuit. The PAM8403 is packaged in a 24-pin SOP while the PAM8303S is housed in a SOP-8. They are ideal for applications such as digital photo frames, MP4/PMP, GPS navigators, PC speakers, portable-DVD players, LCD-monitors, and cell-phones.
"Measuring 20dBuV/m at the critical 200MHz frequency, PAM8x03 offers the industry's lowest EMI and is the first suitable solution for applications such as AM/FM radio, TV or products normally associated with radio interference," said Johnston Chen, President and chief executive officer of PAM.
The PAM8x03 family of products is now in full production.
