The TMP411 and TMP411D devices are remote temperature sensors with a built-in local temperature sensor. The remote temperature sensor, diode-connected transistors are typically low-cost, NPN- or PNP-type transistors or diodes that are an integral part of microcontrollers, microprocessors, or FPGAs.

Remote temperature accuracy is ±1°C (TMP411) or ±0.8°C (TMP411D) for multiple device manufacturers, with no calibration needed. The two-wire serial interface accepts SMBus write byte, read byte, send byte and receive byte commands to program the alarm thresholds and to read temperature data.

Features that are included in the TMP411 and TMP411D devices are: series resistance cancellation, programmable non-ideality factor, programmable resolution, programmable threshold limits, user-defined offset register for maximum accuracy, minimum and maximum temperature monitors, wide remote temperature measurement range (up to 150°C), diode fault detection, and temperature alert function.

The TMP411 device is available in VSSOP-8 and SOIC-8 packages and TMP411D is available in SOT23-8 package.
