Integrated temperature sensors
give digital output
A novel pair of digital-output temperature sensor ICs are ideal for extended temperature measurement in communications, consumer, environmental, industrial and instrumentation applications
Packaged in a tiny 6-lead SOT-23 package, the TMP100 and TMP101 contain a 12bit analogue-to-digital convertor, silicon temperature sensor and a two-wire serial interface. The devices feature an ultra-low supply current of 45uA and a shutdown current of 0.1uA, making them well suited for low-power applications.

Requiring no external components, the TMP100 and TMP101 are capable of reading temperatures within 2.0C accuracy and a resolution of 0.0625C.
'TI's new line of digital temperature sensors offer an unmatched combination of low power, accuracy, resolution and low price which will benefit any portable temperature measurement or temperature control application', said Tadija Janjic, strategic marketing engineer for TI's high-performance linear products.
The TMP100 and TMP101 are ideal for space-sensitive, low-power systems such as portable and battery-operated devices, automotive applications, electronic test equipment, notebook computers and process control equipment.
In addition, it is very useful for monitoring temperature in power supply systems.
The TMP100 and TMP101 feature SMBus and I2C interface compatibility, with the TMP100 allowing up to eight devices on one bus.
The TMP101 offers an SMBus alert function with up to three devices per bus.
Both devices operate from 2.7 to 5.5V and are specified over the -55 to +125C temperature range.
The TMP100 and TMP101 are available in 6-lead SOT-23 packages.
Suggested resale price in 1000 piece quantities is $0.75 for the TMP100 and $0.80 for the TMP101.
