AD7705 Dual 16 bit ADC Data Acquisition Module Input Gain Programmable SPI Interface TM7705

AD7705 Dual 16-bit ADC Data Acquisition Module

Features of AD7705 Dual 16-bit ADC Data Acquisition Module:

• 3.3V or 5.0V DC power supply
• MCU interfaces : SPI
• The main ADC chip : TM7705 (Shenzhen Tianwei original brand new chip, and AD7705 chip is fully compatible)
• 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.
• The input circuit strip dividing resistor and RC filter, enabling customers to change their own gain range
• The chip with a programmable gain amplifier, the gain range : 1-128 times
• Chip buffer amplifier with input for direct connection of sensors.
