S-58LM20A

S-58LM20A Series www.sii-ic.com © Seiko Instruments Inc., 2007-2015 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 ±2.5°C (−55°C to +130°C) −11.77 mV/°C Typ.
