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

Note 1. All voltage are measured with respect to the ground pin, unless otherwise specified.
Note 2. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is functional, but do not guarantee specific performance limits. Electrical Characteristics state DC and AC electrical
specifications under particular test conditions which guarantee specific performance limits. This assumes that the device is within Operating
Ratings. Specifications are not guaranteed for parameters where no limit is given, however, the typical value is a good indication of device
performance.
Note 3. The maximum power dissipation must be derated at elevated temperature and is dictated by TJMAX, ΘJA and the ambient temperature TA.
The maximum allowable power dissipation is PDMAX = (TMAX - TA)/ ΘJA . The typical junction-to-ambient thermal resistance, when board
mounted, is 170/W for package SOP-08, and PSOP-08, and is 107/W for package number PDIP-08
Note 4. Human body model, 100pF discharged through a 1.5kΩ resistor.
Note 5. Machine model, 200 pF - 240 pF discharged through all pins.
