DESCRIPTION

The TSYS02D is a single chip, temperature sensor.

It provides factory calibrated data corresponding to the measured temperature.

The data is provided via I

2

C interface.

The temperature range is -40°C ... +125°C while the resolution is 0.01°C.

The TSYS02D can be interfaced to any microcontroller by an I

2

C interface.

The TDFN8 package provides smallest size and very fast time response.

FEATURES APPLICATIONS

ABSOLUTE MAXIMUM RATINGS

Absolute maximum ratings are limiting values of permitted operation and should never be

exceeded under the worst possible conditions either initially or consequently. If exceeded by

even the smallest amount, instantaneous catastrophic failure can occur. And even if the

device continues to operate satisfactorily, its life may be considerably shortened.
