ADC3643: apply the same signal into ADC3643IRSBT , but reading is different?

Part Number: ADC3643

hi Sir

I use the ADC3643IRSBT  to monitor the V/I , to monitor the impulse signal

Apply the signal into the CH1, the ADC reading is correct

apply the signal into  the  CH2, the ADC reading is Error

the ch1,ch2 is the same signal.

ex: ch1 into the sin waveform, i can read the right waveform, but the same waveform into ch2, the reading is error, 

input 5k hz  triangle wave as left figure

But adc reading is incorrect as right figure
