в—Џ PROGRAMMABLE HIGH/LOW SETPOINTS The TMP122 and TMP124 are SPI-compatible temperature
sensors available in SOT23-6 and SO-8 packages. Requiring only a pull-up resistor for complete function, the TMP122
and TMP124 temperature sensors are capable of measuring
temperatures within 2В°C of accuracy over a temperature
range of –40°C to +125°C, with operation up to 150°C.
Programmable resolution, programmable set points and shut
down function provide versatility for any application. Low
supply current and a supply range from 2.7V to 5.5V make …
