Smallest Package and PC Board Space The LT1675 has the internal gain set for +2V/V or 6dB, because itis designed to drive a double-terminated so I or 75 I cable that has an inherent 6dB loss. There are several advantages to setting the gain internally. This topology eliminates six gain set resistors, reduces the pin count of the package and eliminates stray capacitance on the sensitivity feedback node. The LT1675 fits into the small
