Name: AD7705 dual 16-bit ADC data acquisition module
Model: AD7705
The collected data is very stable, real 16-bit valid words.
Provide Chinese materials, module schematics and examples (C51, AVR, STM8, STM32F4)
STM32-V5 development board wiring method: plug directly into the interface socket of NRF24L01.
Features:
1, 3.3V or 5.0V DC power supply
2. MCU interface: SPI
3. Main ADC chip: TM7705 (new chip, fully compatible with AD7705 chip)
4. External LM285-2.5 reference voltage (original).
5. The input circuit has voltage-dividing resistor and R-C filter, which is convenient for customers to change the gain range by themselves.
6, chip with programmable gain amplifier, gain range: 1-128 times
7, the chip's internal input with buffer amplifier, you can directly connect the sensor.
