PCF8591 AD / DA chip introduced: The PCF8591 Is a monolithically integrated, and a separate power supply, low-power, 8-bit CMOS data acquisition devices. The PCF8591 has the four analog inputs, one analog output and a serial I2C bus interface. PCF8591 three address pins A0, A1 and A2 can be used in hardware address programmed 8 PCF8591 device allows access to the same I2C bus, without the need for additional hardware. On the PCF8591 device input and output of the address, control and data signals are transmitted in serial fashion via the two-wire bidirectional I2C bus. PCF8591 main performance indicators: ? single power supply ? 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 ? 8-bit successive approximation A / D converter ? 1 analog output DAC gain Description: 1.The module chips adoption PCF8951 2.The module supports external voltage input of the 4-way acquisition (voltage input range of 0-5v) 3.AD acquisition ambient light intensity by exact numerical module integrated photoresistor 4.Module integrated thermistor accurate value of the ambient temperature can be collected by AD 5.Module integrated 1 channel 0-5V voltage input acquisition (the blue potentiometer to adjust the input voltage) 6.Module with power indicator (module after power indicator lights) 7.Module with DA output indicator, when the module DA output interface voltage reaches a certain value, will light up the board DA output indicator, the higher the voltage, the more obvious indicator brightness; 8.Module PCB size: 3.6cm * 2.3cm 9.Standard dual panel thickness of 1.6mm, layout nice, surrounded by a through-hole 10.Aperture: 3mm, easily fixed Module Interface Description: The module on the left and right, respectively, to expand outside the 2-way pin header, respectively, as follows: The left:the AOUT chip DA output interface AINO chip analog input interface 0 AIN1 chip analog input interface 1 AIN2 chip analog input interface 2 AIN3 chip analog input interface 3 The right:SCL IIC clock interface connected to the microcontroller IO port SDA IIC digital interface connected microcontroller IO port GND module with the external ground VCC power interface add-3.3v-5v Module red shorting cap instructions Module 3 red short cap respectively function as follows: P4: connect to P4 short circuit cap, choose the access circuit thermistor P5: connect to P5 short circuit cap, select photoresistor access circuit P6: connect to P6 shorting cap, select 0-5V adjustable voltage access circuit 1) We accept PayPal payment ONLY. inkfrog terapeak inkFrog Analytics On May-29-16 at 08:54:05 PDT, seller added the following information:
