The AN7135 is a power amplifier circuit of 7.5W (15.0V, 3) 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.
