Hi,
I am using ADS1293 for my heartrate application. I configured ADS1293 for 3-channels, it is working perfectly.
I want to test single channel application with no RL drive. But I don't see any signal on channel except some 50Hz Noise.
I modified my hardware as mentioned in ADS1298 datasheet as shown below.
I am using 0.1uF for Cblock, and 4.7MOhm for Rpull-up, which results in 0.34Hz cutoff frequency.
My ADS1293 register settings are like this.
IN1 - RA
IN2 - LA
SELRD = 00
PACE2RLD = RLDREF
Can some guide me where I am going wrong?
Regards
Lakshmikanth.
Lakshmikanth,
I am trying to get you help on this. Please refer to this post

Lakshmikanth,
Here's a presentation that provides more information on this topic.
Thanks,

Hello Vishy,
Thanks for referring the presentation. It was very useful. After going through the presentation, We decided to use the solution recommended in the PPT which is to use External MUX with input protection resistors.
Below is our current configuration which is being used for 3 channel with internal MUX.
For single channel configuration, we want to use either LA or RA to be connected to the RLDOUT. Is it possible to not use the external MUX and connect RLDOUT directly to LA or RA??

Lakshmikanth.
