Consult LTC Marketing for parts speciﬁed with wider operating temperature ranges.

* Ground pins are not internally connected. For best channel isolation,

connect to ground.

The ● denotes speciﬁcations which apply over the speciﬁed operating

temperature range, otherwise speciﬁcations are at TA = 25°C. For each ampliﬁer: VCM = 2.5V, VS = 5V, ⎯E⎯N = 0V, pulse tested, unless

otherwise noted. (Note 4)
