3.Maximum power consumption: 3V voltage, maximum power consumption is 1mW
4.Standby current: A maximum of 8uA
Hardware introduction and description
1.Board size: 30*16mm
2.Board function description 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
Remove the R2,R5 can improve the input impedance
