The PCF8591 Module is an 8-bit Analog-to-Digital (ADC) and Digital-to-Analog Converter (DAC) with an I2C communication interface. It is designed to convert analog signals to digital for microcontrollers that lack an ADC, while also providing a DAC for generating analog outputs. This module is widely used in sensor interfacing, signal processing, and data acquisition applications.
Features of PCF8591 Module - ADC/DAC Converter Module:
- 4-channel 8-bit ADC and 1-channel 8-bit DAC
- I2C communication for simple integration with microcontrollers
- On-board potentiometer for testing the analog input functionality
- On-board light and temperature sensors for demonstration purposes
- Adjustable reference voltage for customized signal processing
- Compact and easy-to-use design with clear pin labeling
Specifications of PCF8591 Module - ADC/DAC Converter Module:
- Operating Voltage: 2.5V - 6V DC
