1 / 18 page LM61 www.ti.com SNIS121I – JUNE 1999 – REVISED FEBRUARY 2013 LM61 2.7V, SOT-23 or TO-92 Temperature Sensor Check for Samples: LM61 1 FEATURES DESCRIPTION The LM61 is a precision integrated-circuit 2 • Calibrated Linear Scale Factor of +10 mV/°C temperature sensor that can sense a −30°C to • Rated for Full −30° to +100°C Range +100°C temperature range while operating from a • Suitable for Remote Applications single +2.7V supply. The LM61's output voltage is linearly proportional to Celsius (Centigrade) • UL Recognized Component temperature (+10 mV/°C) and has a DC offset of +600 mV. The offset allows reading negative APPLICATIONS temperatures without the need for a negative supply. • Cellular Phones The nominal output voltage of the LM61 ranges from +300 mV to +1600 mV for a −30°C to +100°C • Computers temperature range. The LM61 is calibrated to provide • Power Supply Modules accuracies of ±2.0°C at room temperature and ±3°C • Battery Management over the full −25°C to +85°C temperature range. • FAX Machines The LM61's linear output, +600 mV offset, and factory • Printers calibration simplify external circuitry required in a single supply environment where reading negative • HVAC temperatures is required. Because the LM61's • Disk Drives quiescent current is less than 125 μA, self-heating is • Appliances limited to a very low 0.2°C in still air. Shutdown capability for the LM61 is intrinsic because its inherent low power consumption allows it to be powered directly from the output of many logic gates. Table 1.
