TC1047/TC1047A

Precision Temperature-to-Voltage Converter

General Description

Features

• Supply Voltage Range:

The TC1047 and TC1047A are linear voltage output

temperature sensors whose output voltage is directly

proportional to the measured temperature. The

TC1047 and TC1047A can accurately measure

temperature from -40°C to +125°C. With the TC1047,

the supply voltage can vary between 2.7V and 4.4V.

The power supply range of the TC1047A is from 2.5V

to 5.5V.

- TC1047: 2.7V to 4.4V

- TC1047A: 2.5V to 5.5V

• Wide Temperature Measurement Range:

- -40^oC to +125^oC

• High Temperature Converter Accuracy:

- ± 2^oC, Max, at 25°C

• Linear Temperature Slope: 10 mV/°C (typ.)

• Available in 3-Pin SOT-23B Package

• Very Low Supply Current:

- 35 µA Typical

The output voltage range for these devices is typically

100 mV at -40°C, 500 mV at 0°C, 750 mV at +25°C and

1.75V at +125°C. A 10 mV/°C voltage slope output

response allows for

a

predictable temperature

measurement over a wide temperature range. The

TC1047 and TC1047A are packaged in 3-pin SOT-23B

packages, making them ideal for space-critical

applications.

Applications

DETAILED DESCRIPTION

The TC1047 and TC1047A have an output voltage that

varies linearly with temperature in degrees Celsius.

Figure 4-1 shows a plot of the output voltage versus

temperature for the TC1047 and TC1047A. The

temperature slope is fixed at 10 mV/°C and the output

voltage at 0°C is 500 mV.

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.
