3 Description

The TMP461 device is a high-accuracy, low-power

remote temperature sensor monitor with a built-in

local temperature sensor. The remote temperature

sensors are typically low-cost discrete NPN or PNP

transistors, or substrate thermal transistors or diodes

that are integral parts of microprocessors,

microcontrollers, or field-programmable gate arrays

(FPGAs). Temperature is represented as a 12-bit

digital code for both local and remote sensors, giving

a resolution of 0.0625°C. The two-wire serial interface

accepts the SMBus communication protocol with up

to nine different pin-programmable addresses.

Advanced features [such as series resistance

cancellation, programmable nonideality factor (η-

factor), programmable offset, programmable

temperature limits, and a programmable digital filter]

are combined to provide a robust thermal monitoring

solution with improved accuracy and noise immunity.

The TMP461 is ideal for multi-location, high-accuracy

temperature measurements in a variety of

communication, computing, instrumentation, and

industrial applications. The device is specified for

operation over a supply voltage range of 1.7 V to

3.6 V, and a temperature range of –40°C to 125°C.
