CMOS TEMPERATURE SENSOR IC
Rev.3.1_00
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.
Features
• Accuracy against temperature
• Linear output voltage
• Nonlinearity
• Operation in wide range of power supply voltage
• Low current consumption
• Built-in operational amplifier
• Output voltage referred to VSS
• Lead-free, Sn 100%, halogen-free*1
