AD7705 Dual 16-bit ADC data acquisition module SPI interface programmable input gain TM7705

Product Description

AD7705 Dual 16-bit ADC data acquisition module SPI interface programmable input gain TM7705

Name: AD7705 Dual 16-bit ADC data acquisition module

Model: AD7705

Data collection is very stable, true 16-bit effective word.

This product by Ann Fuller electronic design and production, providing the Chinese data, the module schematics and routines (C51, AVR, STM8, STM32F4)

All routines are Ann Fuller electronic original, we can provide technical support. Some manufacturers plagiarism our information, not provide native support, please pay attention to recognize.

  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 interfaces: SPI

3, the main ADC chip: TM7705 (Shenzhen Tianwei original brand new chip, and AD7705 chip is fully compatible)

4, an external reference voltage LM285-2.5 (imported genuine original). Part of the low-end domestic counterparts using TL-431 is not a number as a reference, temperature stability and accuracy of the level difference. Please spotted.

5, the input circuit strip dividing resistor and RC filter, enabling customers to change their own gain range

6, the chip with a programmable gain amplifier, the gain range: 1-128 times

7, chip buffer amplifier with input for direct connection of sensors.
