A-3 NOTE Purchase of Philips I2C components conveys a license under the Philips I2C patent to use the components in the I2C system, provided the system conforms to the I2C specifications defined by Philips. Audio Amplifier ICs 1-1 INTRODUCTION 1 INTEGRATED POWER WITH PHILIPS AUDIO AMPLIFIER ICs Few people realize that one of the world's first ICs was an audio power amplifier from Philips. This delivered a mere 25 mW into a hearing-aid earpiece and incorporated just three transistors and 2 resistors. Not surprisingly, we've made many advances since that initial introduction. Advances that have led to ICs such as the TDA8551 incorporating digital volume control with a control range of more than 80 dB. Or the hi-fi TDA1514A, which can deliver 50 W ­ more than two thousand times the power of that first integrated amplifier. These are just two of the extensive range of audio ICs we now supply for a whole host of applications ­ including portable radio and recorders, car radios, multimedia systems, hi-fi TV, radio and music centres, and digital audio systems. What's more, advanced internal protection circuitry completely eliminates danger of damage from thermal runaway, shortcircuits and electrostatic discharge. Providing a level of circuit reliability formerly the exclusive preserve of professional systems, and, moreo
