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:
- -40oC to +125oC
• High Temperature Converter Accuracy:
- ± 2oC, 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.”
