The TMP03/TMP04 is a monolithic temperature detector that generates a modulated serial digital output that varies in direct proportion to the temperature.
The TMP03 and TMP04 are monolithic temperature detectors from Analog Devices that generate a modulated serial digital output varying in direct proportion to the device temperature. They utilize an onboard sensor and a precision digital modulator to provide a ratiometric encoding format independent of clock drift errors. The TMP04 offers a CMOS/TTL-compatible output, while the TMP03 features an open-collector output suitable for isolated circuits.
