Hi TI members:
This is Hung and I have a HW problem for ECG application by using TI INA333 and TLV2454.
It execute ADC conversion by MCU after the RA/LA signal pass through a series of INA333 and TLV2452 Amp.
However, the ADC result and waveform before ADC seems not correct and I don't have any idea about it so far.
Please kindly help to review the schematic and advise me if any
(Condition: the 1V65 had reworked to analog GND(AGND) and removed R29, R39 two RES)
Schematic:

LEAD2
Thanks & Best Regards
