INA240-Q1: Questions on bandwidth

Part Number: INA240-Q1

Hi, team,

Just check with you about below questions on INA240-Q1 bandwidth.

1. How to understand below 400kHz bandwidth? Is 400kHz applied for all version INA240-Q1 regardless of 20/50/100/200 gain?

2. If so, for gain=200 device, the initial amplifier bandwidth should be very high. please help confirm this information.

Thanks.

Johnny

  • Johnny,

    1. Yes, the bandwidth is the same for all gain variants of the device. 

    2. What do you mean by "initial" amplifier bandwidth? The A4 variant has 400kHz bandwidth, same as all other variants. One difference to note as you've shown above is that the A4 variant takes slightly longer to settle out (9.8us vs. 9.6us)

    Please also note that there is an additional spec for distortion of 100kHz, again for all variants.
