Hello
My customer intends to choose MAX9814.
1)
Would you please let us know about the MAX9814's Maximum Input Voltage VIN_MAX = 100mVp-p (THD 1%) means?
My understanding is, the condition in this case is GAIN = VDD (set to 40dB), and if an input higher than this is applied, the output will begin to distort, even with the AGC enabled.
Is this correct?
So, if the GAIN is set to Unconnected (60dB), the input must be reduced to, say, 10mVp-p or less, or the output will be distorted even with the AGC enabled.
Is this correct?
2)
Looking at the left side of Figure 1 on page 8 of the data sheet, even when an input of 160-180mVp-p, which is higher than 100mVp-p,
is actually applied, enabling the AGC eliminates distortion.
Is the GAIN condition in this case GAIN = VDD (40dB)?
The Maximum Input Voltage VIN_MAX=100mVp-p has a margin, so even with an input of 160-180mVp-p, if AGC is enabled, distortion will be eliminated.
Am I correct in understanding this?
Best Regards
