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:

Thanks & Best Regards

  • Hello Hung,

    I am moving your post to the Precision Amplifiers forum that covers the TLV2454 device.
    I'm sure you'll find an answer here.
