OFFSET CURRENT: 100fA max., 10fA typical (with 0V applied to
inputs and outputs).
ISOLATION: Path (Signal to Signal): >2×10
Common (Signal to Chassis): >10
SETTLING TIME: <2.5s to 400fA (all pathways) after 10V applied
(typical).
CROSSTALK (1MHz, 50Ω Load): <–70dB.
INSERTION LOSS (1MHz, 50Ω Load): <–0.2dB typical.
3dB BANDWIDTH:
(50Ω Load, 50Ω Source): 30MHz typical.
(1MΩ Load, 50Ω Source): 40MHz typical.
RELAY DRIVE CURRENT (per crosspoint): 17mA.
