AD7705 Dual 16 bit ADC Data Acquisition Module Input Gain Programmable SPI Interface TM7705
Description:
- Name: AD7705 Dual 16-bit ADC data acquisition module
- Model: AD7705
- Data collection is very stable, the real 16 valid words.
- This product by Ann Fuller electronic design and production, to provide Chinese data, the module schematics and routines (C51, AVR, STM8, STM32F4)
- STM32-V5 development board wiring methods: directly into the interface socket NRF24L01 on the can.
Features:
1,3.3V or 5.0V DC power supply
2, MCU interface: SPI
3, the main ADC chip: TM7705 (new chip factory in Shenzhen Tianwei, and AD7705 chip is fully compatible)
4, external LM285-2.5 reference voltage (imported genuine authentic)
5, the input circuit with a voltage divider resistors and RC filter, enabling customers to change their own gain range
6, the chip programmable gain amplifier with a gain range: 1-128 times
7, with a chip buffer amplifier input can be directly connected to the sensor.
Front view: (the actual delivery, 4P pin is not soldered to facilitate the customer's own choice of welding direction)
