the LTC6373 has a nice option with the V+OUT pin for the supply of the output amplifier, where one can have a high supply voltage like +-15V for the input amplifiers in order to have a large input voltage range, and have a lower supply voltage for the output amplifiers in order to protect the inputs of the ADC driven by the differential amplifier.
Unfortunately, the IC somehow misses the complementary V-OUT pin.
Was this option omitted during the chip design, or is the V-OUT node just bonded down to the V- pad because of lack of a 14th package pin?
If the latter is the case, will there be a version with the V-OUT brought out to a pin using a different package with more available pins?
I apologized for the delayed response. I'm already looking into this, and I'll get back to you as soon as I can.
Upon checking with the primary contact for the LTC6373. A separate output negative supply wouldn't add much in terms of functionality, because the LTC6373 already have the capability to shift the output common mode voltage via the Vocm pin.
The LTC6373 is a fully differential output, which is why the two outputs will always be symmetrical around Vocm; therefore, it's not possible for one output to swing more than the other.
May I know the reason why you're looking for a separate V-OUT pin? Or do you have any specific application in mind for this kind of use case?
