FS1015 supply voltage 3.3V allowed?

Question

is digital bit-calibration changed, when operated only at 3.3 V?

Hello, 
 Thanks for reaching out Renesas Engineering Community. 
 Could you please specify the exact orderable part number of the sensor you are using? 
 In case of FS1015, please let me inform you that this in an EOL product and we do not recommend it for new designs.

 I would suggest to you to use the FS3000 which is our active air velocity sensor module.

 Also in case you are supplying the sensor with 3.3 V I would suggest to you to supply 5 V to the sensor, since this value is the recommended one as mentioned in the datasheet: 
 
 And back to your question now if my understanding is correct. Your question is that in case 3.3V are supplied to the sensor VDD , if the values here showing the association between the analog output volts and velocity will be different? Is that correct?
