AN7135
Dual 7.5W Low Frequency Power Amplifier Circuit
s Overview
The AN7135 is a power amplifier circuit of 7.5W (15.0V,
3Ω) output. It can provide stereo operation since two
amplifiers are incorporated in a chip. Static circuit current
is very smaller than conventional IC for power amplifier,
and various protective circuits are incorporated, thus pro-
viding high reliability. For its feature of very small static
circuit current, it is best suitable for dry cell operating sets
(e.g. radio cassette recorder). It requires smaller number
of external components because it has little distortion and
low noise and can support the stand-by condition.
s Features
• Small static circuit current
• Stand-by condition supported
• Good oscillation stability
• Little unwanted radiation to RF portion of AM/FM
• Little distortion
• Low noise
• Small shock noise at power ON/OFF, stand-by ON/OFF
• Fewer external components
