Introduction
The Texas Instruments LM75AEVM evaluation module (EVM) helps designers evaluate the operation and
performance of the LM75A. The LM75A is an industry-standard digital temperature sensor with an
integrated Sigma-Delta analog-to-digital converter with a digital I2C interface. The LM75A provides 9-bit
digital temperature readings with an accuracy of ±2°C from -25°C to 100°C and ±3°C from -55°C to
125°C. It has an Over-temperature Shutdown (O.S.) pin that can be used in Comparator or Interrupt
mode.
The EVM contains one LM75A digital temperature sensor. It comes pre-assembled with the LM75A, and
the jumper header allows the end user to select the desired slave ID address on board. The EVM kit
includes a USB2ANY interface board. The evaluation board communicates through the MSP430
microcontroller using the USB2ANY interface board to provide I2C bus. The USB2ANY interface board is
used to relay the information from the EVM to USB2ANY via the PC running the LabVIEW evaluation
software.

and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
