ADS1192ECG-FE: DB9 ECG cable

Part Number: ADS1192ECG-FE
Other Parts Discussed in Thread: ADS1192

Hi Team,

Our customer has some inquiries below regarding the DB9 ECG cables.

Recently I have purchased the ADS1192ECG-FE evaluation board for one of our projects . The purpose was to acquire very low amplitude analog signals (micro volt) generated by one of our in-house built biosensor and convert it to a digital form. I have been reading the User guide. Now I understand the the board works with DB9 ECG cables (6 electrode). My question is: is it possible to use the ECG cable mentioned as a two electrode input? What is your suggestion? Does TI have any recommendations for the cables?

Regards,

Danilo

    Hi,

    If the customer has the EVM board in hand, they can try inject some test signal right away with different gain settings by the EVM's GUI.

     (micro volt) might be challenge; but they can try it with the EVM with different gain settings to see what outcome will be.  If the signal is really too small, then they will need to implement their own Pre-Amp circuit to amplify the signal first and then convert the signal from single end to differential end and then feed the amplified signal to the positive input of ADS1192 with the GND goes into the negative input.

    We are not ECG cable expert so we don't know whether such ECG cable is capable of conducting the signals of the customers application, and we cannot recommend. But, customer can test.

    Thanks.
