TC1046

High Precision Temperature-to-Voltage Converter

Features

General Description

• Supply Voltage Range: 2.7V to 4.4V

The TC1046 is a linear output temperature sensor

whose output voltage is directly proportional to

measured temperature. The TC1046 can accurately

measure temperature from -40°C to +125°C.

• Wide Temperature Measurement Range:

-40^oC to +125^C

• High Temperature Converter Accuracy:

± 2^oC, Max, at 25°C

• Linear Temperature Slope: 6.25mV/^oC

• Very Low Supply Current: 35A Typical

• Small 3-Pin SOT-23B Package

The output voltage range for these devices is typically

174mV at -40°C, 424mV at 0°C, 580 mV at +25°C, and

1205mV at +125°C. A 6.25mV/°C voltage slope allows

for the wide temperature range.

The TC1046 is packaged in a 3-Pin SOT-23B package,

making them ideal for space critical applications.

 2001-2012 Microchip Technology Inc.

Note the following details of the code protection feature on Microchip devices:

•

Microchip products meet the specification contained in their particular Microchip Data Sheet.

•

Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the

intended manner and under normal conditions.

•

There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our

knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data

Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

•

Microchip is willing to work with the customer who is concerned about the integrity of their code.

Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not

mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our

products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts

allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
