The INA143 difference amplifier datasheet states that the device supports G=10 and G=0.1 when connected in difference amplifier configuration. However, the datasheet only gives specifications for the G=10 case.
The bandwidth there is given as 0.15MHz for the G=10 case (where the internal op amp will see a gain of 11), but I'm interested in the bandwith at G=0.1 (where the op amp's gain is 1.1). Given that op amps typically have a 20db/decade gain/frequency relation, can I extrapolate that the bandwidth in the G=0.1 configuration will likely be around 1MHz or above?
I plan to use the amplifier inside a feedback loop, so good bandwidth will be essential for stability.
