Dear team,

Customer have design INA188 in their system but looking for similar spec and with higher slew rate solution.

Could you share your suggestion with us? Thanks.

If you have two more different slew rate level can offer to customer for option, that will be better.

    Hello Ben,

    The INA828 is a higher performing part that provides faster slew rate and higher bandwidth, for highest performance there is the INA821, with the widest bandwidth and fastest slew rate. 

    An parametric comparison is available here for all three devices
