LMT88 2.4V, 10µA, SC70, DSBGA Temperature Sensor

FEATURES

DESCRIPTION

The LMT88 is a precision analog output CMOS

integrated-circuit temperature sensor that operates

over a −55°C to 130°C temperature range. The

power supply operating range is 2.4 V to 5.5 V. The

transfer function of LMT88 is predominately linear, yet

has a slight predictable parabolic curvature. The

accuracy of the LMT88 when specified to a parabolic

transfer function is ±1.5°C at an ambient temperature

of 30°C. The temperature error increases linearly and

reaches a maximum of ±2.5°C 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 130°C and −55°C. Decreasing the

power supply voltage to 2.4 V changes the negative

extreme to −30°C, while the positive remains at

130°C.

APPLICATIONS

•

Industrial

HVAC

Disk Drives

Automotive

Portable Medical Instruments

Computers

Battery Management

Printers

The LMT88 quiescent current is less than 10 μA.

Therefore, self-heating is less than 0.02°C in still air.

Shutdown capability for the LMT88 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.

Power Supply Modules

FAX Machines

Mobile Phones

Automotive

The LMT88 is a cost-competitive alternative to

thermistors.
