AN246: Driving the Analog Inputs of a SAR A/D Converter
Driving any A/D Converter (ADC) can be challenging if all
issues and trade-offs are not well understood from the
beginning. With Successive Approximation Register (SAR)
ADCs, the sampling speed and source impedance should be
taken into consideration if the device is to be fully utilized. In
this application note we will delve into the issues surrounding
the SAR Converter’s input and conversion nuances to insure
that the converter is handled properly from the beginning
of the design phase. We will also review the specifications
available in most A/D Converter data sheets and identify
the important specifications for driving your SAR. From this
discussion, techniques will be explored which can be used
to successfully drive the input of the SAR A/D Converter.
Since most SAR applications require an active driving device
at the converter’s input, the final subject will be to explore
the impact of an operational amplifier on the analog-to-digital
conversion in terms of DC as well as AC responses.
AN693: Understanding A/D Converter Performance
Specifications
The purpose of this application note is to describe the
specifications used to quantify the performance of A/D
converters and give the reader a better understanding of
the significance of those specifications in an application.
Although the information presented here is applicable to all
A/D converters, specific attention is given to features of the
standalone and PIC® microcontrollers with A/D converters.
AN793: Power Management in Portable Applications:
Understanding the Buck Switchmode Power Converter
Powering today’s portable world poses many chal lenges for
system designers. The use of batteries as a prime power
source is on the rise. As a result, a burden has been placed
on the system designer to create sophisticated systems
utilizing the batteries full poten tial.
Each application is unique, but one common theme rings
through: maximize battery capacity usage. This theme
directly relates to how efficiently the energy from the
batteries is converted and transferred to the system load. No
single method is ideal for all applications. Lin ear regulators,
switched capacitor charge pumps and inductor based
switchmode power converters are all employed. Each method
has its associated advantages and disadvantages. It is the
particular application with its individual requirements that
determines which method will be the best to use.

Charging Lithium-Ion/Lithium-Polymer Batteries
This application note focuses on the fundamentals of
charging Lithium-Ion/Lithium-Polymer batteries. In particular,
a linear, stand-alone solution utilizing Microchip’s MCP73841
will be explored.
AN948: Efficiently Powering Nine White LEDs with the
MCP1650
The number of applications that utilize white LEDs has
steadily increased due to the increased usage of Liquid
Crystal Displays (LCDs) in automotive and cellular telephone
displays, PDAs, handheld electronic games and computer
monitors. In order to view the information on these displays,
a light source is needed. Typically, this light source has been
provided by Cold Cathode Florescent Tubes (CCFT). However,
since designers are tasked with improving efficiency, lowering
cost and decreasing size, white LEDs are now being used.
Powering white LEDs, which have a forward drop (VF) of
3.6V, typically, becomes more difficult when the application
requires multiple LEDs. In this Application Note, a solution
using the MCP1650 is discussed and shown to be greater
than 85% efficient.
AN960: New Components and Design Methods Bring
Intelligence to Battery Charger Applications
This application note will describe a typical intelligent battery
charger power system application. As with most real life
applications, there are many demands made on the power
system designer to protect the system in the case of battery
removal, plugging the battery in backwards, reverse polarity
at the input, a battery shorting and even more unimaginable
situations. A complete battery charger, fuel gauge system
design will be presented as an example of the mixed
signal design method. Battery reference material and basic
switchmode power supply converter trade-offs are covered in
the beginning of this application note.
