TM7705 Analog to Digital Converter Module [16 bit]

Description:
The AD7705 is a complete 16-bit, low-cost, Sigma Delta ADCs intended for dc and low-frequency ac measurement applications. 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. Their low power (1 mW max @ 3 V) allows them to be used in loop-powered, battery-powered or locally-powered applications. The on-chip Programmable Gain Amplifier with gain settings from I through 128 can accommodate both low-level and high-level analog inputs with no external signal conditioning hardware. This ADC board is able to sample an analog signal with 16 bits at 500 samples per second.

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.
