AD7705 DUAL 16-BIT ADC DATA ACQUISITION TM7705 MODULE

The AD7705 is a complete analog front end for low frequency measurements. It is a 2 channel device and sends data using SPI protocols. Gain settings, signal polarity, and update rate selection can be configured in software using the input serial port. The device is ideal for use in a smart microcontroller or DSP based system.

Features:

• • 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.

Package Includes:

• • 1 x AD7705 16 Bit Dual Channel ADC Data Acquisition Module With SPI Interface TM7705
