Analog Interconnect 16-bit Embedded Control Solutions 5 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, handheld 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. ■ 16-bit Delta-Sigma ADC ■ 12-bit 10 MSPS Pipeline ADC ■ 10-bit 1 MSPS DAC ■ Dual op amps ■ eXtreme Low Power: 18 nA deep sleep, 180μA/MHz Run MPLAB® Starter Kit for PIC24F Intelligent Integrated Analog (DM240015) This kit includes 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.
