TMP04FSZ [Analog Devices]

The TMP03/TMP04 are monolithic temperature detectors with a modulated serial digital output proportional to temperature. They feature low cost, 3-pin package, ±1.5°C accuracy (typ) from –25°C to +100°C, specified –40°C to +100°C, operation to 150°C, power consumption 6.5 mW max at 5 V, flexible open-collector output on TMP03, CMOS/TTL-compatible output on TMP04, and low voltage operation (4.5 V to 7 V). The onboard sensor generates a voltage proportional to absolute temperature, compared to an internal voltage reference, and input to a precision digital modulator. The ratiometric encoding format is independent of clock drift errors. Overall accuracy is ±1.5°C (typical) from –25°C to +100°C, with excellent transducer linearity. The digital output of TMP04 is CMOS/TTL compatible, and the open-collector output of TMP03 is capable of sinking 5mA. They are rated for operation over –40°C to +100°C in low cost TO-92, SO-8, and TSSOP-8 packages, with operation extending to 150°C with reduced accuracy.
