PIC16F1783-I/SP產(chǎn)品概述
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.
The analog functions of the PIC® MCUs scale from the low-cost and low-power PIC16 and PIC24 families to dsPIC® Digital Signal Controllers for the highest
performance digital control.
Applications:
This flexibility and efficiency benefit multiple 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)
Power conversion
Efficient motor control
Lighting
Power measurement and monitoring
Energy harvesting equipment
Solar inverters
Microchip's Intelligent Analog solutions reduce component count enabling smaller, more cost-effective boards and simplified, higher-performance designs. In addition, designers benefit from increased analog topology flexibility utilizing the MCU’s programmable analog interconnects.
