1 / 13 page LM19 www.ti.com SNIS122E – MAY 2001 – REVISED MARCH 2013 LM19 2.4V, 10µA, TO-92 Temperature Sensor Check for Samples: LM19 1 FEATURES DESCRIPTION The LM19 is a precision analog output CMOS 2 • Rated for Full −55°C to +130°C Range integrated-circuit temperature sensor that operates • Available in a TO-92 Package over a −55°C to +130°C temperature range. The • Predictable Curvature Error power supply operating range is +2.4 V to +5.5 V. The transfer function of LM19 is predominately linear, • Suitable for Remote Applications yet has a slight predictable parabolic curvature. The • UL Recognized Component accuracy of the LM19 when specified to a parabolic transfer function is ±2.5°C at an ambient temperature APPLICATIONS of +30°C. The temperature error increases linearly and reaches a maximum of ±3.8°C at the • Cellular Phones temperature range extremes. The temperature range • Computers is affected by the power supply voltage. At a power • Power Supply Modules supply voltage of 2.7 V to 5.5 V the temperature range extremes are +130°C and −55°C. Decreasing • Battery Management the power supply voltage to 2.4 V changes the • FAX Machines negative extreme to −30°C, while the positive • Printers remains at +130°C. • HVAC The LM19's quiescent current is less than 10 μA. • Disk Drives Therefore, self-heating is less than 0.02°C in still air. Shutdown capability for the LM19 is intrinsic because • Appliances its inherent low power consumption allows it to be powered directly from the output of many logic gates KEY SPECIFICATIONS or does not necessitate shutdown at all. • Accuracy at +30°C ±2.5 °C (max) • Accuracy at +130°C & −55°C ±3.5 to ±3.8 °C (max) • Power Supply Voltage Range +2.4V to +5.5V • Current Drain 10 μA (max) • Nonlinearity ±0.4 % (typ) • Output Impedance 160 Ω (max) • Load Regulation – 0µA < IL< +16 µA 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
