Description:
AD7705 2 Channel ADC Converter Module is designed based on the chip of the same name, which is a series of converter ICs, and is used to convert analog-to-digital signals (ADC) in electronic systems.
The resolution of this ADC converter is 16 bits and consists of two separate channels, and this module is powered with a voltage of 3.3 volts to 5 volts.
The communication protocol of this product is SPI, which is a synchronous serial interface and most microcontrollers have this connection
The pins of this module are as follows:
VCC: The power supply side;
GND: Ground;
DRDY: Logic output;
DOUT: Serial data output;
DIN: Serial data input;
SCK: The serial clock;
CS: Chip Selection;
RST: Reset terminal;
AIN1+: Sampling points of the anode;
AIN1-: Sampling points of the negative; //Get rid of R3 can make differential input
AIN2+: Sampling points of the anode;
AIN2-: Sampling points of the negative; // Get rid of R6 can make differential input
Application:
Reading analog sensors
Increasing the analog input of the microcontroller
