DESCRIPTION
The PT2338 is a stereo power amplifier designed for
the audio equipment; it is possible to delivery up to
150mW power to the 16Ω loads. Overall voltage gain
is determine by the external resistors, for some
application needs higher common mode reject
performance to canceling common mode noises, the
input port of the PT2338 is configuration as differential
input. Very low quiescent current and low voltage
operation capability let it become a best choice for the
portable audio application.
APPLICATIONS
• Portable media player
• Wireless headset
• Mobile phone
• LCD TV
• Mini compo
• PC audio
• Other audio applications
