Overview AN12943A is an one-chip IC for the stereo speakers which can output

1 W by 8 Ω , headphone amplifiers, line amplifiers and electronic

volumes. Since the headphone amplifier is a dual power supply system which uses a DC-DC converter to create the negative power source, an output capacitor is not necessary. Also the AN12943A is built-in power saving on/off function automatically detecting input signal to save the power of speaker amplifier. Features y Speaker amplifier

1 W × 2-channel: 8 Ω , VCC = 5 V

Dual power supply system doesn't require output capacitor. y Built-in automatic power saving function. It detects input signals and switches on/off (with the on/off switch for the auto power saving). y Built-in electronic volume and line amplifier Applications y Notebook PC Unit: mm HSOP056-P-0300A AN12943A Audio signal processing IC for notebook PC

Please carry out the thermal design with sufficient margin such that the power dissipation will not be exceeded, based on the conditions of power supply, load and surrounding temperature. Although indicated also in the column of the maximum rating, the maximum rating becomes an instant and the marginal value which must not exceed. It sufficiently evaluates, and I use-wish-do so that it may not exceed certainly. Moreover, don't impress neither voltage nor current to pin which is not indicated. It may destroy in both cases. 2. Please pay attention in the pattern layout in order to prevent damage due to short circuit between pins. In addition, for the pin configuration, please refer to Pin Descriptions. 3. Please absolutely do not mount the LSI in the re verse direction on to the printed-circuit-board. It might be damaged when the electricity is turned on. 4. Please do a visual inspection on the printed-circuit-board befo re turning on the power supply, otherwise damage might happen due to problems such as a solder-bridge between the pins of the semiconductor device. Also perform a full technical verification on the assembly quality, because the same damage possibly can happen due to conductive substances, such as solder ball, that adhere to the LSI during transportation. 5. Please take notice in the use of this product that it might break or occasionally smoke when an abnormal state occurs such as output pin, pin 34 and pin 36 (capacitor connect pin 1, 2 for charge pump), pin 38 and pin 39 (V SS) − power supply pin short, output pin, pin 34 and pin 36, pin 38 and pin 39 − GND short, or output-to-output-pin short (load short), pin 34 − pin 36 short. And, safety measures such as an installation of fuses are recommended because the extent of the above-mentioned damage and smoke emission will depend on the current capability of the power supply. 6. When using the LSI for model deployment or new products, perform fully the safety verification including the long-turm reliability for each product.

Consult our sales staff in advance for information on the following applications:

Special applications (such as for airplanes, aerospace, automobiles, traffic control equipment, combus- tion equipment, life support systems and safety devices) in which exceptional quality and reliability are required, or if the failure or malfunction of the products may directly jeopardize life or harm the human body.
Any applications other than the standard applications intended. (5) The products and product specifications described in this material are subject to change without notice for modification and/or improvement. At the final stage of your design, purchasing, or use of the products, therefore, ask for the most up-to-date Product Standards in advance to make sure that the latest specifica- tions satisfy your requirements. (6) When designing your equipment, comply with the guaranteed values, in particular those of maximum rat- ing, the range of operating power supply voltage, and heat radiation characteristics. Otherwise, we will not be liable for any defect which may arise later in your equipment. Even when the products are used within the guaranteed values, take into the consideration of incidence of break down and failure mode, possible to occur to semiconductor products. Measures on the systems such as redundant design, arresting the spread of fire or preventing glitch are recommended in order to prevent physical injury, fire, social damages, for example, by using the products. (7) When using products for which damp-proof packing is required, observe the conditions (including shelf life and amount of time let standing of unsealed items) agreed upon when specification sheets are individually exchanged.
