CM8662IP

Manufacturer Part Number
CM8662IP
Description
Audio amplifier, Single channel, PDIP, 8-Pin
Manufacturer
Champion Microelectronic Corp.
Datasheet
GENERAL DESCRIPTION
The CM8662 is a bridge-connected audio power amplifier
capable of delivering typically 675mW of continuous average
power to an 8Ω load with 1% (THD) from a 5V power supply.
Boomer audio power amplifiers were designed specifically to
provide high quality output power with a minimal amount of
external components. Since the CM8662 does not require
output coupling capacitors, bootstrap capacitors, or snuuber
networks, it is optimally suited for low-power portable systems.
The CM8662 features an externally controlled, low-power
consumption shutdown mode, as well as an internal thermal
shutdown protection mechanism.
The unity-gain stable CM8662 can be configured by external
gain-setting resistors.
