Product Description PCF8591 Analog to Digital AD/DA converter The PCF8591 is a single-chip, single-supply low power 8-bit CMOS data acquisition device with four analog inputs, one analog output and a serial I2C-bus interface Three address pins A0, A1 and A2 are used for programming the hardware address, allowing the use of up to eight devices connected to the I2C-bus without additional hardware Address, control and data to and from the device are transferred serially via the two-line bidirectional I2C-bus. Features: Operating voltage: 2.5-6V Low standby current Through the I2C bus serial input / output PCF8591 by 3 hardware address pins addressing Sampling rate PCF8591 I2C bus rate decided 4 analog inputs programmable as single-ended or differential inputs Automatic incremental channel selection PCF8591 analog voltage range from VSS to VDD PCF8591 built-in track and hold circuit 8-bit successive approximation A / D converter through an analog output DAC gain module chip using PCF8951 Size: 3.6cm * 2.3cm Pins definition: The AINO chip analog input interface. AIN1 chip analog input interface AIN2 chip analog input interface AIN3 chip analog input interface The right side of the SCL IIC clock interface to access the microcontroller IO port The SDA IIC digital interface connected microcontroller IO port GND module to an external VCC power supply interface external 3.3v-5v Module red jumper instructions for use Module three red short circuit cap, respectively, the role are as follows: P4 connected to the P4 jumper, select thermistor access circuit P5 connected to P5 jumper to select the photo-resistor access circuit P6 connected to the P6 jumper, to select 0-5V adjustable voltage access circuit
