TMP03FT9Z

TMP03 is a serial digital output thermometer. It is a monolithic temperature detector that generate a modulated serial digital output that varies in direct proportion to the temperature of the device. An on-board sensor generates a voltage precisely proportional to absolute temperature which is compared to an internal voltage reference and input to a precision digital modulator. The ratiometric encoding format of the serial digital output is independent of the clock drift errors common to most serial modulation techniques such as voltage-to-frequency converters. It is widely used in application such as isolated sensors, environmental control systems, computer thermal monitoring, thermal protection, industrial process control, power system monitors etc.
