TLV320ADC5140: input impedance tolerance

Kelvin Lo
Prodigy 250 points
Part Number: TLV320ADC5140

Tool/software:

Hi TI team,

We are facing the ADC gain tolerance issue of our product during MP. We would like to know the input impedance tolerance of the ADC IC. We need this information to redefine the gain and output power for the production tolerance. Thanks!

Circuit

    Hi Kelvin,

    The input impedance has a variation of 0.5% (1 sigma) and tolerance has a worst case of 20%. This is a factor performance mode chosen, flexibility of input impedance configurability, and input configuration (AC or DC coupled).
