PCF8591 module AD/DA conversion module analog/digital to analog conversion DuPont line (มีสต็อกสินค้าในประเทศไทยพร้อมจัดส่ง)
PCF8591 is a monolithically integrated, individually powered, low power, 8-bit CMOS data acquisition device. The PCF8591 has four analog inputs, one analog output, and one serial I2C bus interface. The three address pins A0, A1 and A2 of the PCF8591 can be used for hardware address programming, allowing access to eight PCF8591 devices on the same I2C bus without additional hardware. The address, control, and data signals for the inputs and outputs on the PCF8591 device are transmitted serially over a two-wire bidirectional I2C bus.
PCF8591 main performance indicators:
★ single power supply
★ PCF8591 operating voltage range 2.5V-6V
★ low standby current
★ serial input / output through I2C bus
★ PCF8591 through 3 hardware address pin addressing
★ PCF8591 sampling rate by I2C Bus speed decision
★ 4 analog inputs can be programmed as single-ended or differential inputs
★ Auto-increment channel selection
★ PCF8591 analog voltage range from VSS to VDD
★ PCF8591 built-in track-and-hold circuit
★ 8-bit successive approximation A/D converter
★ DAC gain through 1 analog output
The second baby description
1 module chip uses PCF8951
2 module to support external 4-channel voltage input acquisition (voltage input range 0-5v)
3 module integrated photoresistor, can be collected by AD ambient light intensity accurate value
4 module integrated thermistor, can pass AD Accurate value of the collection ambient temperature
5 Module integrated 1 channel 0-5V voltage input acquisition (adjust the input voltage through the blue potentiometer)
6 module with power indicator (the indicator will light after powering the module)
7 module with DA output indicator, when When the output voltage of the module DA reaches a certain value, the DA output indicator on the board will be illuminated. The higher the voltage, the more obvious the brightness of the indicator light.
8 Module PCB size: 3.6cm*2.3cm
9 Standard double panel, board thickness 1.6mm, layout Beautiful and elegant, there are through holes around, the aperture is: 3mm, convenient to fix the
three-module interface.
The left and right sides of the module are respectively extended with 2 pin headers, which are as follows:
Left AOUT chip DA output interface
AINO chip analog input interface 0
AIN1 analog input interface chip. 1
AIN2 analog input interface chip 2
AIN3 chip analog input 3
to the right of the interface connected microcontroller clock SCL IIC IO
SDA IIC digital interface connected microcontroller IO port
GND module to the external
VCC power supply interface external 3.3v-5v
Four module red short-circuit cap instructions The
module has three red short-circuit caps, which function as follows:
P4 is connected to the P4 short-circuit cap, select the thermistor access circuit
P5, connect the P5 short-circuit cap, select the photoresistor access circuit
P6 and connect to P6. Short circuit cap, select 0-5V adjustable voltage access circuit
