CMOS TEMPERATURE SENSOR IC
S-58LM20A Series
The S-58LM20A Series is a high-accuracy temperature sensor IC on a
single chip, provides output voltage which is linear against the
temperature change.
Each chip consists of a temperature sensor, a constant current circuit,
and an operational amplifier.
This IC is able to be used under the wide temperature range of –55°C to
130°C. This IC has much better linearity than other conventional
temperature sensors such as thermistor, it is possible to achieve the
extensive application for temperature control.
