DESCRIPTION
These SSRs (LH1541, 1 Form A) are SPST normally
open switches which can replace electromechanical
relays in many applications. The relays provide a low-
capacitance, high-voltage switch contact with high off-
resistance and low switch-offset voltage. These charac-
teristics, combined with high-speed actuation, result in
an SSR which is ideal for small signal and dc instrumen-
tation applications.
The relays are constructed by using a GaAlAs LED for
actuation control and an integrated monolithic die for
the switch output. The die is comprised of a photodiode
array, switch-control circuity, and low-capacitance MOS-
FET switches.
