Block Diagram - Analog Functions

Design Considerations
Almost every board has a least one analog signal with a majority of these analog signals coming from sensors. From Consumer Electronics to Industrial Equipment, analog and sensors really are everywhere! Sensors are inherently analog in nature. There is a rapid growth in sensors as more and more systems require interfacing to real world signals for monitoring and measuring real world events such as temperature, humidity, and light. Interfacing to sensors requires a series of signal-conditioning components in a mixed-signal design that are used for analog signal acquisition, processing, and control. Designing these sensor interfaces can be costly, require many components, and be complex requiring long and costly design cycles.

PSoC is a true programmable embedded system-on-chip integrating configurable analog and digital peripheral functions, memory and a microcontroller on a single chip. PSoC integrates programmable analog resources that can be configured easily through the PSoC Creator Software to be various analog components required to interface to sensors and other analog signals. The flexible analog architecture in PSoC allows users to easily define the Signal Chain they need for their design. PSoC integrates more analog functionality than any other mixed-signal embedded solution available, and also provide high performance and precision analog such as an integrated 20-bit Delta Sigma ADC and 0.2% accurate Voltage Reference.

Application Notes
