ADC32RF44: Increasing SNR

Taketo Sato

Part Number: ADC32RF44

Hello team,

Is there any way to increase effective resolution in case input signal to ADC32RF44 is small compared to 1.35Vpp fullscale specified on datasheet?

Amplyfing the signal before ADC, or averaging with fast sampling is only way?

Best regards,

Taketo,

What is the range of your input? Is using a transformer an option for you?

Hello Jim-san,

Input is 100mVpp maximum.
Thank you, Using a transformer is one option. What else do you come up with?

Hello Jim-san,

Is there any other way to increase SNR?
Is using an amplifier or a tranceformer needed?

Taketo,

Using decimation mode will increase SNR.
