LMV551-Q1: Max Capacitive Load under Recommended Operating Conditions

Part Number: LMV551-Q1
Other Parts Discussed in Thread: LMV551

Dear Team,

what is the maximum capacitive load that can be driven from the output of the LMV551-Q1?

Thanks and best regards,

B

    Hi Basel,

    Without compensation, the LMV551-Q1 should try to keep the cap loads below 100pF - this is mentioned in section 7.4.1.1 of the datasheet. With compensation, you can drive larger cap loads.

    Do you have a particular circuit or application that we can assist with?

    Hi Basil,

    the LMV551 is a micropower OPAmp and is optimized for very low supply current and not for high capacitance drive capability. See section 7.4.1.1 and figure 1. So, I would strongly recommend to use a compensation method as shown in section 7.4.1.1.1 or 7.4.1.1.2.
