Texas Instruments (LM19CIZ/NOPB)Temperature Sensor IC, Voltage, ± 2.5°C

Product OverviewThe LM19CIZ/NOPB is an analog output CMOS Temperature Sensor operates over a -55to +130°C temperature range. The power supply operating range is +2.4 to +5.5V.The transfer function of LM19CIZ/NOPB is predominately linear, yet has a slightpredictable parabolic curvature. The accuracy of the sensor when specified to aparabolic transfer function is ±2.5°C at an ambient temperature of +30°C. Thetemperature error increases linearly and reaches a maximum of ±3.8°C at thetemperature range extremes. The temperature range is affected by the powersupply voltage. At a power supply voltage of 2.7 to 5.5V the temperature rangeextremes are +130°C and -55°C. Decreasing the power supply voltage to 2.4Vchanges the negative extreme to -30°C, while the positive remains at +130°C. TheLM19CIZ/NOPB quiescent current is less than 10µA. Therefore, self-heating isless than 0.02°C in still air.Predictable curvature errorUL recognized component10µA Maximum drain current±0.4% Typical nonlinearity160R Maximum output impedanceGreen product and no Sb/BrProduct InformationIC Output Type: VoltageSensing Accuracy Range: ± 2.5°CSensing Temperature Min: -55°CSensing Temperature Max: +130°CSensor Case Style: TO-92No. of Pins: 3PinsSupply Voltage Min: 2.4VSupply Voltage Max: 5.5VProduct Range: -MSL: -
