NOTES: The PA0367A is a modified version of the Pulse PA0367 which was tested and approved by Linear Technology for use with the

LT3420. The PA0367 has now been discontinued. the PA0367A has the same mechanical footprint and size as the PA0367 and meets the

requirements of the LT3420 specifications.
