We see from your search that you're looking for information on the term "QFN",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Audio amplifier simplifies entertainment design from
Texas Instruments (April 2006-), which we summarised at the time by saying "Audio line driver integrates a charge pump to allow a complete audio output signal chain to run from a single 3.3V power supply".
The same day,
we featured the news release Audio codec and headphone driver are united from
Wolfson Microelectronics: "Offers longer battery life in portable media players and multimedia handsets with reduced external component requirements".
In February 2008, we covered the news from STMicroelectronics
concerning its EMIF01-1003M3 and EMIF02-1003M6
- take a look at Compact protectors cover ESD and EMI
which says: "Both devices meet IEC61000-4-2 level 4 for ESD protection and feature low line-to-earth capacitance of 30pF to preserve high-speed signal integrity".
Take a look also at the news release from Elmos Semiconductor, Sensor chip detects motion,
as well as Supervisors sequence up to five power supplies from Maxim Integrated Products,
and Dual regulator has core and I/O voltages covered from Linear Technology Corp.
