ISO122: ISO122 soic package for new design

S.G.
Prodigy 40 points
Part Number: ISO122
Other Parts Discussed in Thread: ISO224, AMC1411

Hi,

In page 20 of the datasheet ISO122 soic packages are marked as active. I would like to ask if you still recommend this isolated amplifier for a new design with an intended life cycle and support of 15 years.

Kind regards

Spyros

    Hi Spyros,

    The ISO122 is nearly 30 years old now!  You can find our policy on part longevity at this link.  If you are interested, please take a look at the ISO224 which is a newer device that has a similar input voltage range to the ISO122 but uses a smaller package and only needs single high/low side supply.  If you need the clearance that the ISO122 provides, another alternate part for you would be the AMC1411.  The AMC1411 only has a 0-2V input range, but provides 14mm of clearance.
