AD7705 Dual Way 16 bit ADC Data Acquisition Module Input Gain Programmable SPI Interface Board
1. External connect LM285-2.5 reference voltage (imported original). Some peers use low-end domestic TL-431 as the benchmark, the temperature stability and accuracy is not an order of magnitude.
2. Input circuit with voltage divider resistance and R-C filter, to facilitate customers to change their own gain range.
3. In-chip programmable gain amplifier, gain range: 1-128 times.
4. The input buffer with amplifier in the chip can connect the sensor directly.
