LM61 2.7V, SOT-23 or TO-92 Temperature Sensor

Check for Samples: LM61

FEATURES

DESCRIPTION

The LM61 is

precision integrated-circuit

•

Calibrated Linear Scale Factor of +10 mV/°C

Rated for Full −30° to +100°C Range

Suitable for Remote Applications

UL Recognized Component

temperature sensor that can sense a −30°C to

+100°C temperature range while operating from a

single +2.7V supply. The LM61's output voltage is

linearly proportional to Celsius (Centigrade)

temperature (+10 mV/°C) and has a DC offset of

+600 mV. The offset allows reading negative

temperatures without the need for a negative supply.

The nominal output voltage of the LM61 ranges from

+300 mV to +1600 mV for a −30°C to +100°C

temperature range. The LM61 is calibrated to provide

accuracies of ±2.0°C at room temperature and ±3°C

over the full −25°C to +85°C temperature range.

APPLICATIONS

•

Cellular Phones

Computers

Power Supply Modules

Battery Management

FAX Machines

Printers

The LM61's linear output, +600 mV offset, and factory

calibration simplify external circuitry required in a

single supply environment where reading negative

temperatures is required. Because the LM61's

quiescent current is less than 125 μA, self-heating is

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.
