Combined LDO/Voltage reference vs discrete
« on: July 06, 2024, 10:08:29 pm »
I'm making a breakout for a Hamamatsu micro-spectrometer c12880ma which needs 5V and a buffer + SE->Diff conversion. I'm using OPA2392 for this, which has an Iq of < 3ma.

Is there anything good or bad about using, say, an ADR3650 w/ its 70ma sourcing capability vs an LDO + a more general voltage reference?

In total, the current draw @ 5V is something like 40ma max including the amps, sensor and a 1MSPS ADC.
