Dual 16-bit ADC Data Acquisition SPI Module Board AD7705

  • Was  RM50.00 
  • RM19.00

  • Product Code: AD7705 Module
  • Availability: In Stock

The AD7705 is a complete 16-bit, low-cost, Sigma Delta ADCs intended for dc and low-frequency ac measurement applications. Their low power (1 mW max @ 3 V) allows them to be used in loop-powered, battery-powered or locally-powered applications. The on-chip Programmable Gain Amplifier with gain settings from I through 128 can accommodate both low-level and high-level analog inputs with no external signal conditioning hardware. This ADC board is able to sample an analog signal with 16 bits at 500 samples per second.



  • Two Fully Differential Input Channel ADCs
  • Ability to Buffer the Analog Input
  • Highly accurate 16 bit ADC
  • Programmable Gain Amplifier 1 - 128 times and RC filter
  • Part peers using low-end domestic TL-431 is not a number as a reference, temperature stability and accuracy of the level difference
  • 16-Lead DIP, 16-Lead SOIC and TSSOP Packages



  • Working voltage: 3.3 - 5.0V DC
  • Voltage Reference: On-board LM285-2.5
  • Programmable gain amplifier range: 1 - 128 times
  • MCU interface: SPI
