Overview
BOOKLY MICRO CM8662 1.
7W CMOS AUDIO AMP GENERAL DESCRIPTION FEATURES The CM8662 is a bridge-connected audio power amplifier ‹ No output coupling capacitors, bootstrap capacitors or capable of delivering typically 1.
7W of continuous average snubber circuits are necessary.
power to an 6Ω load from a 5V power supply and up to 2W if ‹ SOP, SOP with Power Pad or DIP package.
DIP8 package.
Boomer audio power amplifiers were designed ‹ Unity-gain stable specifically to provide high quality output power with a minimal ‹ External gain configuration capability amount of external components.
Since the CM8662 does not ‹ CMOS technology , save power , require output coupling capacitors, bootstrap capacitors, or ‹ higher efficiency than traditional bipolar amplifier snuber networks, it is optimally suited for low-power portable systems.
KEY SPECIFICATION The CM8662 features an externally controlled, low-power ‹ THD at 0.
8W continuous average output power at 1kHz consumption shutdown mode, as well as an internal thermal into 8Ω 0.
5% (max) shutdown protection mechanism.
‹ Output power at 10% THD+N at 1kHz into 8Ω 1.
5W (typ) The unity-gain stable CM8662 can be configured by external ‹ Shutdown Current 0.
7μA (typ) gain-setting resistors.
APPLICATIONS ‹ Walkie-talkie ‹ LCD-TV / monitor ‹ Toys and Games ‹ USB speaker ‹ Digital recorder PIN CONFIGURATION DIP/SOP (Top View) 1 SHUTDOWN Vo2 2 BYPASS GND 3 +IN VDD 4 -IN Vo1 8 7 6 5 2004/05/30 www.
