AN12943A
Audio signal processing IC for notebook PC
„ Overview
Unit: mm
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
y Headphone amplifier
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

y Usage notes
1. 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 reverse 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 before 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 (VSS) − 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.

Request for your special attention and precautions in using the technical information
and semiconductors described in this material
(1) An export permit needs to be obtained from the competent authorities of the Japanese Government if any of
the products or technical information described in this material and controlled under the "Foreign Exchange
and Foreign Trade Law" is to be exported or taken out of Japan.
(2) The technical information described in this material is limited to showing representative characteristics and
applied circuits examples of the products. It neither warrants non-infringement of intellectual property right
or any other rights owned by our company or a third party, nor grants any license.
(3) We are not liable for the infringement of rights owned by a third party arising out of the use of the technical
information as described in this material.
(4) The products described in this material are intended to be used for standard applications or general electronic equipment (such as office equipment, communications equipment, measuring instruments and household appliances).
Consult our sales staff in advance for information on the following applications:
• Special applications (such as for airplanes, aerospace, automobiles, traffic control equipment, combustion 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 specifications satisfy your requirements.
(6) When designing your equipment, comply with the guaranteed values, in particular those of maximum rating, 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.
