AN7135

ICs for Audio Common Use 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 providing 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. 5.9±0.25 7.7±0.3 7.8±0.25 ø 3.6 12 Unit : mm 29.96±0.3 28.0±0.3 20.0±0.2 0.6 R1.8 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 1 1.2±0.1 0.35 – 0.05 3.5±0.3 12 11 8 7 + 0.1 Fin-attached 12-lead SIP package (HSIP012-P-0000A) s Block Diagram VCC 3 10 2 Input Circuit Drive Circuit SEPP Output Circuit 1 Bias Circuit Over Temperature Protection Crossover Distortion 6 5 Input Circuit Drive Circuit SEPP Output Circuit 4 GND (Input) 9 GND (Output) 2.54 0.6±0.1 29.6±0.3 AN7135 s Pin Name Pin No. 1 2 3 4 5 6 Input Ch.1 Ripple filter/Stand-by Controller GND (Input) Input Ch.2 Negat...
