Description of PCF8591 ADC DAC Converter Module

The PCF8591 Module is a breakout/prototype board based on the PCF8591 IC, a single-chip, low-power CMOS data acquisition device. It integrates four analog inputs, one analog output, and an I²C bus interface, making it ideal for applications requiring analog-to-digital and digital-to-analog conversion.

With three address pins (A0, A1, A2), up to eight devices can be connected on the same I²C bus without additional hardware. The device includes analog input multiplexing, a track-and-hold function, an 8-bit ADC, and an 8-bit DAC, supporting flexible data acquisition and control applications.

This module also integrates a photoresistor, thermistor, and adjustable potentiometer for real-time sensing of light, temperature, and voltage.


Key Features

  • Wide operating voltage range (2.5V – 6V) with low standby current.
  • I²C serial communication with 3 hardware address pins (A0–A2), supporting up to 8 devices on the same bus.
  • 4 analog input channels, configurable as single-ended or differential, plus 1 analog output (DAC).
  • 8-bit ADC and DAC resolution with built-in track-and-hold circuit for stable sampling.
  • Supports 0–5V external analog signal acquisition for versatile measurements.
  • Integrated photoresistor for light detection and thermistor for temperature sensing.
  • Onboard potentiometer (0–5V adjustable) for voltage testing and calibration.
  • Power indicator LED and DAC output indicator LED for real-time status monitoring.
