Draft — The document is a draft version only. The content is still under
internal review and subject to formal approval, which may result in
modifications or additions. Ampleon does not give any representations or
warranties as to the accuracy or completeness of information included herein
and shall have no liability for the consequences of use of such information.
Short data sheet — A short data sheet is an extract from a full data sheet
with the same product type number(s) and title. A short data sheet is intended
for quick reference only and should not be relied upon to contain detailed and
full information. For detailed and full information see the relevant full data
sheet, which is available on request via the local Ampleon sales office. In
case of any inconsistency or conflict with the short data sheet, the full data
sheet shall prevail.
Product specification — The information and data provided in a Product
data sheet shall define the specification of the product as agreed between
Ampleon and its customer, unless Ampleon and customer have explicitly
agreed otherwise in writing. In no event however, shall an agreement be valid
in which the Ampleon product is deemed to offer functions and qualities
beyond those described in the Product data sheet.
12.3 Disclaimers
Limited warranty and liability — Information in this document is believed to

representations or warranties, expressed or implied, as to the accuracy or
completeness of such information and shall have no liability for the
consequences of use of such information. Ampleon takes no responsibility for
the content in this document if provided by an information source outside of
Ampleon.
In no event shall Ampleon be liable for any indirect, incidental, punitive,
special or consequential damages (including - without limitation - lost profits,

replacement of any products or rework charges) whether or not such
damages are based on tort (including negligence), warranty, breach of
contract or any other legal theory.
Notwithstanding any damages that customer might incur for any reason
whatsoever, Ampleon’s aggregate and cumulative liability towards customer
for the products described herein shall be limited in accordance with the
Terms and conditions of commercial sale of Ampleon.
Right to make changes — Ampleon reserves the right to make changes to
information published in this document, including without limitation
specifications and product descriptions, at any time and without notice. This
document supersedes and replaces all information supplied prior to the
publication hereof.
Suitability for use — Ampleon products are not designed, authorized or
warranted to be suitable for use in life support, life-critical or safety-critical
systems or equipment, nor in applications where failure or malfunction of an
BLS9G2731L-400_LS-400
Product data sheet
Ampleon product can reasonably be expected to result in personal injury,
death or severe property or environmental damage. Ampleon and its
suppliers accept no liability for inclusion and/or use of Ampleon products in
such equipment or applications and therefore such inclusion and/or use is at
the customer’s own risk.
Applications — Applications that are described herein for any of these
products are for illustrative purposes only. Ampleon makes no representation
or warranty that such applications will be suitable for the specified use without
further testing or modification.
Customers are responsible for the design and operation of their applications
and products using Ampleon products, and Ampleon accepts no liability for
any assistance with applications or customer product design. It is customer’s
sole responsibility to determine whether the Ampleon product is suitable and
fit for the customer’s applications and products planned, as well as for the
planned application and use of customer’s third party customer(s). Customers
should provide appropriate design and operating safeguards to minimize the
risks associated with their applications and products.
Ampleon does not accept any liability related to any default, damage, costs or
problem which is based on any weakness or default in the customer’s
applications or products, or the application or use by customer’s third party
customer(s). Customer is responsible for doing all necessary testing for the
customer’s applications and products using Ampleon products in order to
avoid a default of the applications and the products or of the application or
use by customer’s third party customer(s). Ampleon does not accept any
liability in this respect.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those given in
the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
Terms and conditions of commercial sale — Ampleon products are sold
subject to the general terms and conditions of commercial sale, as published
at http://www.ampleon.com/terms, unless otherwise agreed in a valid written
individual agreement. In case an individual agreement is concluded only the
terms and conditions of the respective agreement shall apply. Ampleon
hereby expressly objects to applying the customer’s general terms and
conditions with regard to the purchase of Ampleon products by customer.
No offer to sell or license — Nothing in this document may be interpreted or
construed as an offer to sell products that is open for acceptance or the grant,
conveyance or implication of any license under any copyrights, patents or
other industrial or intellectual property rights.
Export control — This document as well as the item(s) described herein
may be subject to export control regulations. Export might require a prior
authorization from competent authorities.
