My customer has a design that has been working for many months but is now seeing that the I2C communication is being lost with the AD7994. Are there any unpublished or common issues seen around the I2C interface? Thank you!
I am connecting to an AD7994 from an NXP LPC17xx processor. My code is written in C using the Keil compiler. I am able to read data from the AD7994, but it always only returns one 16 bit value. I believe this is from channel 1. I have sent the 0x30 to…
AD7994: Trouble reading anything other than channel 1. I'm using three AD7994s to read some amplified photodiode outputs. It seems that for each ADC, I can only read channel 1.
I'm using the AD7994s in Mode 2 (Command Mode). I initiate a write to…
Currently ADI have the 12 bit resolution in the portfolio, the AD7992 (AD7994 -4 channels) and as mentioned the LTC2451 but the concern is the address was factory set. Is it okay for you to share particular application to be use.
Can you check on your Device Manager and see if you can find AD7993/AD7994 Evaluation Kit? Also, what OS are you working with?
The AD7993/AD7994 normally remain in a shutdown state
while not converting, and power up only for conversions. The
conversion process can be controlled using the CONVST pin.
You may need a rising edge to power up the part. you have to…
