PCF8591 AD/DA chip introduction
PCF8591 is a monolithic integrated, single power supply, low power consumption, 8-bit CMOS data acquisition device. PCF8591 has four analog input, 1 analog output and 1 serial I2C bus interface. Three address pins of PCF8591, A0, A1 and A2 can be used for hardware address programming, allowing 8 PCF8591 devices on the same I2C bus without the need for additional hardware. Address input and output, control and data signals on the PCF8591 device are transfered through dual bidirectional I2C bus, in the form of serial transmission.
PCF8591 main performance index:
Single power supply
operating voltage range of PCF8591: 2.5V to 6V
Low standby current
input/output through I2C bus serial transmission
PCF8591 addressing through three hardware address pins
PCF8591 sampling rate is determined by the rate of I2C bus
4 analog input, can be programmed into single-end or differential input
Automatic incremental channel choosing
PCF8591 analog voltage range from VSS to VDD
PCF8591 built-in track and hold circuit
8-bit successive approximation A/D converter
DAC gain was achieved by 1-way analog output
Product description
1 module chip uses PCF8951
2 module supports external 4-way voltage input collection (voltage input range 0 to 5v)
3 module is integrated with photocell, can collect precise environmental light values through AD
4 module is integrated with thermal resistor, can collect precise environmental temperature values through AD
5 module is integrated with 1-way 0 to 5V voltage input collection (adjust input voltage by blue potentiometer)
6 module include power indicator light (light up when module is power on)
7 module include DA output indicator light, when the DA output voltage of the module interface reaches a certain value, the light will be lit up; the bigger the voltage, the lighter the light will be;
8 module PCB size: 3.6 cm * 2.3 cm
9 standard double-sided board, board thickness 1.6 mm, nice layout, through-hole around, hole diameter:3 mm, easy to fix
