CAT34TS00
1.8 V Digital Temperature
Sensor
Description
CAT34TS00 is a low-voltage digital temperature sensor, which
implements the JEDEC JC42.4 specification. CAT34TS00 measures
temperature every 100 ms over a range of −20°C to +125°C, with a
resolution of 12 bits.
The host communicates with the device via the serial I²C / SMBus
Interface, at either 100 kHz or 400 kHz. Temperature readings can be
retrieved via serial interface. Internally, they are compared to high,
low and critical trigger limits stored in device registers. Over or under
limit conditions can be signaled on the open−drain EVENT pin. These
limits, as well as other settings, can be configured via serial interface.
