Temperature sensing in high-precision applications
5 June 2002, Power Electronics / Power Management

When it comes to precision applications, the demands of a temperature sensor are tested to the maximum: superior accuracy, low power consumption, and a tiny package are just a few of the challenges that it - or they - must answer. Typical high-accuracy thermal management applications use thermistors. However, the thermistor is nonlinear and therefore requires several additional support components to digitise, linearise, and format.

Often, these applications integrate as many as four temperature sensing elements to accomplish this: base stations - to sense the overloads in the power amplifier; portables - to monitor the battery charge rate; instrumentation - in LCD panel temperature measurement; communications - in the frequency synthesizer system to compensate for temperature effects.

The newest member in Analog Devices' temperature sensor family that can address all these requirements in one chip is its ADT7301. This device is an accurate SOT temperature sensor, with a specification of ±0,5°C from 0°C to 70°C. Fully specified for 2,7 V to 5,5 V voltage supplies, it operates over a very broad temperature range, -55°C up to +150°C.

Along with this, the ADT7301offers high accuracy, very low power consumption, and comes in small 6-lead SOT and chip scale packages.

Applications are in: medical instrumentation; portable communication; industrial control; disk drives; and automotive.
