Requiring no external components, the TMP121 and TMP123 are capable of measuring temperatures within 2 °C of accuracy over a temperature range of −40°C to +125 °C. Low supply current, and a supply range from 2.7V to 5.5V, make the TMP121 and TMP123 excellent candidates for low-power applications. The TMP121 and TMP123 are ideal for extended thermal measurement in a variety of communication, computer, consumer, environmental, industrial, and instrumentation applications. Diode Temp.
