2 / 15 page LM50, LM50-Q1 SNIS118E – JULY 1999 – REVISED SEPTEMBER 2013 www.ti.com This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. ABSOLUTE MAXIMUM RATINGS (1) Supply Voltage +12V to −0.2V Output Voltage (+VS + 0.6V) to −1.0V Output Current 10 mA Storage Temperature −65°C to +150°C TJMAX, Maximum Junction Temperature 150°C ESD Susceptibility (2): Human Body Model 2000V Machine Model (Does not apply for LM50-Q1) 250V Charged Device Model 750V (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating the device beyond its rated operating conditions. (2) Human body model, 100 pF discharged through a 1.5 k Ω resistor. Machine model, 200 pF discharged directly into each pin. OPERATING RATINGS (1) Specified Temperature Range: TMIN to TMAX LM50C/LM50-Q1 −40°C to +125°C LM50B −25°C to +100°C Operating Temperature Range −40°C to +150°C θJA (2) 450°C/W Supply Voltage Range (+VS) +4.5V to +10V Soldering process must comply with Reflow Temperature Profile specifications. Refer to http://www.ti.com/packaging.(3) (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating the device beyond its rated operating conditions. (2) Thermal resistance of the SOT-23 package is specified without a heat sink, junction to ambient. (3) Reflow temperature profiles are different for lead-free and non-lead-free packages. ELECTRICAL CHARACTERISTICS Unless otherwise noted, these specifications apply for VS = +5 VDC and ILOAD = +0.5 μA, in the circuit of Figure 2. Boldface limits apply for the specified TA = TJ = TMIN to TMAX; all other limits TA = TJ = +25°C, unless otherwise noted. Parameter Conditions LM50B LM50C/LM50-Q1 Units (Limit) Typical Limit (1) Typical Limit (1) Accuracy (2) TA = +25°C ±2.0 ±3.0 °C (max) TA = TMAX ±3.0 ±4.0 °C (max) TA = TMIN +3.0, −3.5 ±4.0 °C (max) Nonlinearity (3) ±0.8 ±0.8 °C (max) Sensor Gain(Average Slope) +9.7 +9.7 mV/°C (min) +10.3 +10.3 mV/°C (max) Output Resistance 2000 4000 2000 4000 Ω (max) Line Regulation (4) +4.5V ≤ VS ≤ +10V ±0.8 ±0.8 mV/V (max) ±1.2 ±1.2 mV/V (max) (1) Limits are specified to TI's AOQL (Average Outgoing Quality Level). (2) Accuracy is defined as the error between the output voltage and 10mv/°C times the device's case temperature plus 500 mV, at specified conditions of voltage, current, and temperature (expressed in °C). (3) Nonlinearity is defined as the deviation of the output-voltage-versus-temperature curve from the best-fit straight line, over the device's rated temperature range. (4) Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output due to heating effects can be computed by multiplying the internal dissipation by the thermal resistance. 2 Submit Documentation Feedback Copyright © 1999–2013, Texas Instruments Incorporated Product Folder Links: LM50 LM50-Q1 |
