This section describes the S-58LM20A component specifications.
|Components Classification||Temperature sensor|
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 –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.
