Want a Business Partner,
Not Just a Vendor?
Successful companies recognize the value of a strategic
supplier relationship to help them deliver innovative
products to their markets in a timely manner . They trust
their suppliers to furnish quality components for current
design opportunities as well as provide technology
road maps and innovative solutions to stay ahead of
tomorrow’s design trends .
Microchip Technology provides low-risk product
development, lower total system cost and faster time
to market to more than 45,000 of these successful
companies worldwide . Headquartered in Chandler, Arizona,
Microchip offers outstanding technical support along with
dependable delivery and quality .
Founded in 1989, Microchip’s business model is based on
a series of guiding values that aim to establish successful
customer partnerships by exceeding expectations for
products, services and attitude . Continuous improvement,
technology innovation and the pursuit of the highest
quality possible drive Microchip’s company culture .
The result is a worldwide organization dedicated to
delivering whole product solutions which include high
performance silicon devices, easy-to-use development
tools, outstanding technical support and sophisticated
technical documentation .
Direct control over manufacturing resources allows
shortened design and production cycles . By owning the
wafer fabrication facilities and the majority of the test
and assembly operations, and by employing proprietary
statistical process control techniques, Microchip has been
able to achieve and maintain high production yields .
Need Additional Support and Resources?
Microchip is committed to supporting its customers by
helping design engineers develop products faster and
more efficiently . Customers can access three main
service areas at www .microchip .com . The Support area
provides a fast way to get questions answered . The
Sample area offers evaluation samples of any Microchip
device . microchipDIRECT provides 24-hour pricing,
ordering, inventory and credit for convenient purchasing
of all Microchip devices and development tools . This
site also features online programming capabilities .
Finally, the Training area offers opportunities to expand
your knowledge with Microchip’s online web seminars
and hands-on courses at our worldwide Technical
Training Centers . Our seminars and training classes are
designed to fit your schedule and offer an overview of
many product, development tool and application topics .
Visit
www .microchip .com/training
for class content
and schedules .
Have you ever encountered a technical dilemma at a
critical point in your design development and your supplier
was not available to answer your questions? Microchip’s
first ever 24/7 global technical support line brings
technical support resources any time help is needed .
Because some technical problems require hands-on
assistance in order to be resolved quickly, Microchip
has also developed a global team of field applications
engineers and field sales engineers for local assistance .
Are Quality and Delivery a Concern?
Microchip’s quality systems are certified according to
the International Organization for Standards/Technical
Specification (ISO/TS)-16949:2002 requirements . This
demonstrates that the Company’s quality systems meet
the most stringent industry quality-management system
standards, resulting in high-quality semiconductor products .

Analog & Interface Product Selector Guide
note 1:
These devices use an external temperature sensor. Accuracy of the total solution is a function of the accuracy of the external sensor.
2:
Maximum accuracy measured at 85°C.
3:
TCN75 idle current is 250 mA. This device also has a Software Shutdown mode that reduces supply current to < 1 mA.
