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, moreover, providing you with a solid guarantee of quality and reliability in your own systems.

A valuable aid to designers
In the following pages you'll find our complete range of audio amplifiers. Intended principally as a designer's first selection guide, the pages give the most important parameters, or at least, those that feature prominently when design criteria are initially being considered. Used in conjunction with our Data Handbook IC01 (which gives more detailed information), this guide provides audio system designers with a ready means of selecting the most appropriate components for their designs. The publication is divided into three application areas: portable radio/audio, car radio and mains-powered systems. Many products, however, may be suitable for several application areas: car audio systems and mains-powered multimedia PCs for example. What's more, many of today's applications for audio amplifier ICs, e.g. musical greeting cards, were unheard of just a few years ago. This means that any subdivision such as that given in this guide can be only a preliminary indication of a product's suitability for a particular application. In using this guide, therefore, designers should cast their net as wide as possible and should consider all likely candidates when looking for a suitable audio IC for their application.

Integrated power
A major feature of our latest range is the high degree of functional power integrated within each package. A functional power that dramatically reduces the peripheral component count of finished equipment, leading to: lower system development costs smaller, more compact circuitry far fewer production problems significantly lower production costs.

No external components required Excellent overall stability Output protected against short-circuit No external heatsink required Low power consumption No switch-on or switch-off clicks Supply voltage range of 3 V to 18 V Fixed closed-loop voltage gain of 39 dB (6 V supply, 8 load)

The proprietary circuit design of these amplifiers makes use of the bridge-tied load (BTL) principle to achieve low-voltage operation without sacrifice of output power. They are therefore primarily intended for battery-powered portable recorders and radios. However, their wide supply voltage range (3 V to 18 V) also makes them suitable for TV. The TDA7052 comes in an 8-pin plastic DIP and is pincompatible with half of the TDA7053 which is in a 16-pin plastic DIP.

Like the TDA1510AQ/1515BQ these are car audio class-B power amplifiers but with internally fixed gain for excellent channel balance (within 1 dB). The three types are virtually identical except for their gain. The TDA1516CQ is identical to the TDA1516BQ except that it consumes very little current in short-circuit to ground condition (typically 5.5 mA) and is only suitable for operation in BTL mode.

Primarily for car audio applications, this IC uses class-H amplifier techniques so that, with a 14.4 V supply and minimal heatsinking, it can deliver 40 W into an 8 load. For the first time, this allows a 4 40 W car radio to be assembled in a standard DIN-sized car radio case. Below 10 W the IC acts as a normal BTL amplifier. At higher outputs, the internal supply voltage is doubled by adding the charge stored on external capacitors. This allows the power output to increase to 40 W. The amplifier comes in a 17-pin plastic SIL power package with the pins bent to DIL format.

This power amplifier normally operates in low-power singleended mode and switches to high-power BTL mode only when large amplitude signals are received from the preamplifer. The TDA1561Q therefore dissipates only about 55% of the power dissipated by a conventional power amplifier (measured at average maximum music power) which means heatsinks can be smaller. Primarily for car audio applications, the amplifier is also ideal for multimedia systems and active loudspeakers. The TDA1561Q comes in a 13-pin plastic SIL power package with the pins bent to DIL format.
