1.8 V Digital Temperature Sensor

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.
