Description:
PCF8591 Module Analog to Digital / Digital-Analog Converter Module
This is a breakout/prototype board designed for the PCF8591 IC. The PCF8591 is a low-power, 8-bit CMOS data acquisition device that operates on a single supply. It features four analog inputs, one analog output, and a serial I²C-bus interface for easy communication.
The module includes three address pins—A0, A1, and A2—which allow you to set the hardware address, enabling the connection of up to eight devices on the same I²C bus without the need for additional hardware. Data transfer to and from the device is done serially via the bidirectional I²C bus.
The PCF8591 offers key features such as analog input multiplexing, an on-chip track-and-hold function, 8-bit analog-to-digital conversion, and 8-bit digital-to-analog conversion. The maximum conversion rate is determined by the speed of the I²C bus.
PCF8591 IC Features:
- Single power supply
- A PCF8591 operating voltage range of 2.5V-6V
- Low standby current
- Via I2C bus serial input/output
- PCF8591 by 3 hardware address pins addressing
- PCF8591 I2C bus speed sampling rate decided
- 4 analog inputs programmable single-ended or differential input
- Automatic incremental channel selection
- PCF8591 analog voltage range from VSS to VDD
- PCF8591 built-in track-and-hold circuit

Module Features:
- The module supports external voltage input of the 4-way acquisition (voltage input range of 0-5v)
- The module integrated photoresistor by AD collection precise value of the ambient light intensity
- Module integrated thermistor by the precise value of the ambient temperature of the AD acquisition
- Module integrated 1 channel 0-5V voltage input acquisition (the blue potentiometer to adjust the input voltage)
- Modules with power indicator (for the module power supply indicator lights)
- Modules with DA output indicator, when the module DA output interface voltage reaches a certain value, will be lit panel the DA output indicator, the higher the voltage, the more obvious indicator brightness
- Module PCB size: 3.6cm x 2.3cm
- A standard double panel, thickness 1.6mm, nice layout, surrounded by a through-hole, aperture: 3mm, convenient fixed.
