LM26EVAL-XPA

LM26EVAL-XPA LM26 Evaluation Kit Manual 1.0 General Description The LM26 Evaluation Kit allows quick connection and evaluation of the LM26CIM5XPA factory preset thermostat. The LM26CIM5-XPA has a trip point setting of +105°C with an accuracy of ±3°C. Header J2 allows you to short the HYST pin of the LM26 to GND thus changing the hysteresis to 10°C. The board comes without the jumper so the HYST pin is HIGH and the part 2°C hysteresis set. The part requires a power supply voltage of 2.7V to 5.5V. J1 allows easy connection of other circuitry to all of the LM26’s pins. Figure 1.

TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications. TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
