说明

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 2°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 versatile for any application. Low supply current, and a supply range from 2.7V to 5.5V, make the TMP122 an excellent candidate for low-power applications.

The TMP122 and TMP124 are ideal for extended thermal measurement in a variety of communication, computer, consumer, environmental, industrial, and instrumentation applications.
