Original Press Release
Ultra-Low-Power Precision Temperature Sensor from STMicroelectronics is Ideal for 3G Cell Phones
Press release date: October 21, 2006
The new device is an analog-output temperature sensor operating over a -55 to +130 degrees C temperature range. At 25 degrees C the precision sensor's temperature-to-voltage accuracy is plus or minus 1.5 degrees C, and it is plus/minus 2.5 degrees C over the entire operating temperature range. The STLM20 is supplied in a tiny 1.0mm x 1.3mm x 0.5mm thick 4-lead UDFN package - as well as in 5-lead SOT323 (SC70) - to meet the demands of space constrained products.
Operating from a supply voltage of 2.4V to 5V, the STLM20 draws a maximum of 8µA over the full temperature range. It is targeted for the RF section of 3G mobile phones and multimedia PDAs, monitoring transmitter power amplifiers to guarantee linearity as required by the W-CDMA (Wideband Code Division Multiple Access) 3G standards. The STLM20 is also suitable for temperature-compensated crystal oscillators and battery chargers and other portable applications, such as GPS devices and medical instruments.
The STLM20 is available now, priced at $0.25 in high volumes. For more information, go to www.st.com/sensors.
