ADXL327 buffering

Hi all,

 

i am using ADXL327 as accelerometer sensor in low noise application. I need to amplify its output voltage with an op amp put in inverting configuration which has low input resistance due to low noise concern.

 

The ADXL327 has an output impedance of 32kohm so do i need to put a unity gain buffer before the inverting amplifier?

 

Best regards
