LM60/LM60-Q1 2.7V, SOT-23 or TO-92 Temperature Sensor

Check for Samples: LM60/LM60-Q1

FEATURES

DESCRIPTION

The LM60/LM60-Q1 is a precision integrated-circuit

temperature sensor that can sense a −40°C to

+125°C temperature range while operating from a

single +2.7V supply. The LM60/LM60-Q1's output

voltage is linearly proportional to Celsius (Centigrade)

temperature (+6.25 mV/°C) and has a DC offset of

+424 mV. The offset allows reading negative

temperatures without the need for a negative supply.

The nominal output voltage of the LM60/LM60-Q1

ranges from +174 mV to +1205 mV for a −40°C to

+125°C temperature range. The LM60/LM60-Q1 is

calibrated to provide accuracies of ±2.0°C at room

temperature and ±3°C over the full −25°C to +125°C

temperature range.

•

Calibrated linear scale factor of +6.25 mV/°C

Rated for full −40°C to +125°C range

Suitable for remote applications

Available in SOT-23 and TO-92 packages

LM60Q is AEC-Q100 Grade 1 qualified and is

manufactured on an Automotive Grade flow.

APPLICATIONS

•

Automotive

Cell Phones & Computers

Power Supply Modules

Battery Management

FAX Machines & Printers

HVAC & Disk Drives

Appliances

The LM60/LM60-Q1's linear output, +424 mV offset,

and factory calibration simplify external circuitry

required in a single supply environment where

reading negative temperatures is required. Because

the LM60/LM60-Q1's quiescent current is less than

110 μA, self-heating is limited to a very low 0.1°C in

still air in the SOT-23 package. Shutdown capability

for the LM60/LM60-Q1 is intrinsic because its

inherent low power consumption allows it to be

powered directly from the output of many logic gates.
