Dear Sir/Madam,
I’m planning to use an LT3902 based constant-current circuit in conjunction with an OPAMP(AD8629). However, since the conditions differ, the LTSpice output doesn’t match the expected values. Could you please review my schematic and offer some advice?
The sensor used in the Wheatstone bridge has been changed, so I intend to redesign it using the LT3902 in a constant-current configuration.



Best & Regards,
Mike Noh
