16-bit Embedded Control Solutions
Intelligent Analog
Summary
Analog design is difficult and consumes precious
development time. Microchip’s intelligent PIC® MCUs
integrate analog functions such as high-performance
Analog-to-Digital Converters (ADCs), Digital-to-Analog
Converters (DACs) and operational amplifiers (op amps),
providing simple-to-use interfaces that ease analog
design. This single-chip solution enables reduced system
noise and provides higher throughput, while dramatically
reducing design time and cost.
Benefi ts of Analog Integration
■ Eliminates the complicated task of debugging the noise
sources that reduce analog signal integrity
■ Removes the bottleneck of communicating to the
microcontroller from analog
■ Provides consistent analog performance that can be
leveraged from design to design, eliminating analog
design rework
■ Through intelligent connections made inside the chip,
the analog is fully controlled by software
■ Benefi ts include a simplifi ed design cycle, board space
savings, faster throughput and better signal integrity
■ Intelligent analog leads to lower-cost designs that are
brought to market faster
Target Applications
■ Environmental quality sensors
■ Portable medical equipment (glucose meters, portable
ECGs, pulse oximeters, blood pressure meters)
■ Industrial equipment (gas sensors, handhald multi-meters,
lab instrumentation, e-meters, sensor arrays)
Featuring the PIC24FJ128GC010 Family
with Intelligent Analog
The PIC24 “GC” Family integrates a precision 16-bit ADC,
high-speed 12-bit ADC, DAC and op amps with interconnect
fabric providing the most analog integration available in
a PIC MCU. With on-chip USB and segmented LCD driver,
this family is ideal for
portable devices with
user interfaces.

MPLAB® Starter Kit for PIC24F Intelligent
Integrated Analog (DM240015)
This kit inlcudes an analog
header for clean analog signals
and plugs into breadboards.
The board includes connections
for microphone, headphones
as well as on-board light and
temperature sensors. The
segmented display showcases custom icons and a scrolling
banner. The board also includes cap touch buttons, USB
connection and easy connection for RF modules.
