Hi,
We are using a LMH6321MR voltage follower at the output of a DAC. The voltage at the buffer's input remains constant with or without any load. When a load of 2K Ohm is connected to the output of the buffer (pin 6) and removed there is a variation of 21mV at the output. For eg. the voltage is 10.0260V but when the load is removed it falls to 10.0050V (The voltage remains at 10.0399V at the input pin 3 of LMH632MR with or without load). The EF and CL pins are pulled up to +15 and +5 respectively.
This is causing a problem because the specification says the variation of voltage with or without load should not be more than 1.2mV. Is there any solution for this problem or any other component that can match the requirement.
Please suggest any tweaks or any other component.
