Other Parts Discussed in Thread: TSW14J50EVM,
Dear TI E2E,
I have two problem which using ADC34J43EVM and capturing by TSW14J50EVM.
I follow the ADC3xxx, ADC3xJxx EVM User’s Guide to setting EVM broad, ADC3000 GUI, and HSDC Pro.
1.
I connect CIN_P to GND.
But the ADC code which record by HSDC is about 8200.
Is this ADC measure voltage = 2 * 8200 / (2^14) ~= 1.00 V?
But the CIN_P seems 0 V.
I not sure which setting is wrong.
2.
I CIN_P input 1V with series resistance of 1k ohm.
In the spec, the input impedance is 6.5k ohm.
But when I measure the voltage of resistance seems very low.
Thanks for your help. I look forward any suggestion from you.
