DRV8305-Q1: datasheet spec clarification

Part Number:DRV8305-Q1

Team, 

Help answer my customer's questions below, please:

Can you help me please with some clarification on datasheet parameters for the Current Sense Amp of the DRV8305NE (…PHPRQ1)? References are specifically to “SLVSD12C –MAY 2015–REVISED SEPTEMBER 2017” datasheet – primarily page 10.

1. Is GERR the tolerance for GCSA? If not, what is GERR relative to as a %?
2. UGB is stated as 2MHz typical at GCSA=10. UGB generally means unity gain bandwidth, so does this mean that at the gain setting of 10V/V the bandwidth is 200kHz? Or is does this parameter mean the bandwidth at GCSA=10 is 2MHz (i.e. unity gain BW = 20MHz)?
3. How does bandwidth vary with temperature? Is it monotonically decreasing with temperature? Increasing with temperature? Other? Having only a typical, am I to infer that the it flat with temperature?
4. How does bandwidth vary with PVDD? Flat within the specified 4.4 to 45v range?

 Thanks!
