Found out what they are... Fixed voltage attenuation with impedance matching. In the AB catalogue as 31421001 and 31421002.

Finding data on chips is sometimes difficult as you know as the number on the chip bears little relation to whats on the datasheet. I was looking for LTSX yesterday, which is all that was on the SMD chip, which turned out to be a LTC1871, bonkers.

Glad you found yours, Andy.
