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.
The operating ambient temperature is from –55C to 130C. 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.
