AD7705 Dual 16 Bit ADC
In stock (can be backordered)
LC AD7705 module is AD acquisition module, there are two full differential input channels. AD7705 inside with a programmable gain amplifier, chip internal input with buffer amplifier, so can directly connected sensor.
- Working voltage: 3.3V or 5.5V;
- MCU interface: SPI;
- Maximum power consumption: 3V voltage, maximum power consumption is 1mW;
- Standby current: A maximum of 8uA.
- The board size: 30*16mm
- The board function description:
VCC: The power supply side;
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
Remove the R2,R5 can improve the input impedance.
