SC-82AB (NP004-A)
SNT-4A (PF004-A)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.
