One Chip AM/FM Radio with Audio Power Amplifier

Description

The integrated circuit TDA1083 includes, with exception
of the FM front end, a complete AM-/FM-radio-circuit
with audio power amplifier. An internal Z-diode

Features

 Large supply voltage range V
 High AM-Sensitivity

= 3 to 12 V

S

stabilizes the supply voltage at VS  13 V, which allows
with the aid of a resistor and a rectifier, the circuit to be
driven by a higher external supply voltage.

Ozone Depleting Substances Policy Statement

It is the policy of Atmel Germany GmbH to

1. Meet all present and future national and international statutory requirements.

2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems
with respect to their impact on the health and safety of our employees and the public, as well as their impact on
the environment.

It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as
ozone depleting substances (ODSs).

The Montreal Protocol (1987) and its London Amendments (1990) intend to severely restrict the use of ODSs and forbid
their use within the next ten years. Various national and international initiatives are pressing for an earlier ban on these
substances.

Atmel Germany GmbH has been able to use its policy of continuous improvements to eliminate the use of ODSs listed
in the following documents.

1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively

2. Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental
Protection Agency (EPA) in the USA

3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C (transitional substances) respectively.

Atmel Germany GmbH can certify that our semiconductors are not manufactured with ozone depleting substances
and do not contain such substances.

We reserve the right to make changes to improve technical design and may do so without further notice.

Parameters can vary in different applications. All operating parameters must be validated for each customer

application by the customer. Should the buyer use Atmel Wireless & Microcontrollers products for any unintended

or unauthorized application, the buyer shall indemnify Atmel Wireless & Microcontrollers against all claims,

costs, damages, and expenses, arising out of, directly or indirectly, any claim of personal damage, injury or death

associated with such unintended or unauthorized use.
