LM20 2.4V, 10A, SC70, micro SMD Temperature Sensor October 1999 LM20 2.4V, 10A, SC70, micro SMD Temperature Sensor General Description The LM20 is a precision analog output CMOS integrated-circuit temperature sensor that operates over a 55C to +130C temperature range. The power supply operating range is +2.4 V to +5.5 V. The transfer function of LM20 is predominately linear, yet has a slight predictable parabolic curvature. The accuracy of the LM20 when specified to a parabolic transfer function is ± 1.5C at an ambient temperature of +30C. The temperature error increases linearly and reaches a maximum of ± 2.5C at the temperature range extremes. The temperature range is affected by the power supply voltage. At a power supply voltage of 2.7 V to 5.5 V the temperature range extremes are +130C and 55C. Decreasing the power supply voltage to 2.4 V changes the negative extreme to 30C, while the positive remains at +130C. The LM20’s quiescent current is less than 10 A. Therefore, self-heating is less than 0.02C in still air. Shutdown capability for the LM20 is intrinsic because its inherent low power consumption allows it to be powered directly from the output of many logic gates or does not necessitate shutdown at all. n n n n n n Battery Management FAX Machines Printers HVAC Disk Drives Appliances Features n n n n Rated for full 55C to +130C range Available in an SC70 and a micro SMD package Predictable curvature error Suitable for remote applications Key Specifications n Acc……
