Hi everyone,
I’ve been working on a small data logging project and recently started testing the AD7705 AD7606 Data Acquisition Module for analog signal reading and noise analysis. It’s quite versatile, offering SPI and parallel interfaces, 16-bit precision, and multi-channel synchronous sampling.
I wanted to ask if anyone here has integrated it successfully with Arduino, STM32, or ESP32 boards:
-
How consistent is the sampling when reading multiple analog channels simultaneously?
-
Any stability issues at higher sampling frequencies (for example, above 100 kS/s)?
-
Does the onboard reference hold stable when connected to external sensors like thermocouples or strain gauges?
-
For the AD7606 version, did you need to modify R1/R2 resistor settings when switching from parallel to SPI mode?
I’m planning to use it in an industrial environment for current and voltage sensing, so long-term stability and noise performance are my main concerns.
Would really appreciate feedback or working examples from anyone who’s used this module in a real project.
Thanks!
