Rev.1.2_00 CMOS TEMPERATURE SENSOR IC S-58LM20A Series 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. This IC is able to be used under the wide temperature range of –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 ±2.5°C (55 to +130°C) 11.77 mV/°C Typ. Ta = 30°C： 2.205 V Typ. Ta = +30°C： 1.515 V Typ. Ta = +130°C： 0.303 V Typ. ±0.4% Typ. (20 to +80°C) VDD = 2.4 to 5.5 V (30 to +130°C) VDD = 2.7 to 5.5 V (55 to +130°C) 4.5 A Typ. (+25°C) 6.0 A Max. (55 to +130°C) Nonlinearity Operation in wide range of power supply voltage Low current consumption Built-in operational amplifier Output voltage referred to VSS Small package Lead-free product SNT-4A, SC-82AB, WLP-4B Applications Compensation of high-frequency circuits such as cellular phones and radio equipment Compensation of oscillation frequency in crystal oscillator LCD contrast compensation Compensation of amplifier gain Compensation of auto focus circuits Temperature detection in battery management Overheating prevention for charged batteries or halogen lights Package Package Name SC-82AB SNT-4A WL……
