Webcast to address wireless power optimisation
Texas Instruments and Avnet Electronics Marketing will present a live Analog eLab webcast on 'Optimising power in low-power wireless systems' on 12th April 2006
Low supply current (50uA), a shutdown feature (0.1uA) and a supply range from 2.7 to 5.5V make the device well suited for low-power applications.
The TMP122 provides programmable resolution (9 to 12bit) and programmable setpoints for the alert pin.
'The TMP122 is the latest addition to TI's growing portfolio of temperature sensors which offers a superior combination of accuracy, resolution, versatility and low power.
Due to its programmable features, small packaging and wide temperature range, the TMP122 will find its place in a very diverse set of applications', said Tadija Janjic, Strategic Marketing Engineer for TI's high-performance linear products.
The TMP122 is optimised for space-sensitive, low-power systems such as computer peripheral thermal protection, notebook computers, cellphones, thermostat controls, battery management and environmental monitoring.
The TMP122 is packaged in an SOT23-6, and is available now from TI and its authorised distributors.
Suggested resale price is $0.99 in 1000-piece quantities.
