Questions about the alternative possibility of ADL5310 and ADL5303

Hi,

I have moved your query to RF and Microwave Community.

Someone here should be able to assist you.

Thanks and regards!

Hello swjung,

Below is how ADL5303 compares to ADL5303:

ADL5303 is wider dynamic range (160 vs 120 dB)

ADL5303 offers PD bias output (ADL5310 does not)

ADL5303 is lower log-linear intercept point (300pA vs 100pA)

ADL5303 is lower Vref (2 vs 2.5V)

ADL5303 is a little less bandwidth

ADL5310 offers log ratio fcn (ADL5303 does not)

ADL5303 requires narrower range of VPOS 

We have no other dual log converters at the moment.

Sorry about the typo, above. Described spec-by-spec is how ADL5310 and ADL5303 compare.

If ADL5303 is not a replacement for ADL5310, please recommend a replacement part.

ADL5310 is more like a dual version of the AD8305. Some specs like log-linear intercept are still different, however, between the two.
