Examples are battery chargers (batteries charge capacities vary with temperature and cell temperature can help determine the optimum point at which to terminate fast charging), crystal oscillators (oscillation frequency varies with temperature) and LCDs (contrast is temperature- dependent and can be compensated if the temperature is known). LM50 Single Supply Celsius Sensor The LM50 is called a Single Supply Celsius Sensor because, unlike the LM35 and LM45, it can measure negative temperatures without taking its output pin below its ground pin (see the Applications Hints section). This can simplify external circuitry in some applications. LM60 Typical Connection 3.2 Current- Output Analog Sensors LM134, LM234, and LM334 Current- Output Temperature Sensors Although its data sheet calls it an adjustable current source , the LM134 is also a current- output temperature sensor with an output current proportional to absolute temperature. 3.3 Comparator- Output Temperature Sensors LM56 Low- Power Thermostat The LM56 includes a temperature sensor (similar to the LM60), a 1.25V voltage reference, and two comparators with preset hysteresis. It will operate from power supply voltages between 2.7V and 10V, and draws a maximum of 200µA from the power supply.
