DESCRIPTION
The PS7122A-1B, -2B and PS7122AL-1B, -2B are solid state relays containing GaAs LEDs on the light emitting
side (input side) and normally close (N.C.) contact MOS FETs on the output side.
They are suitable for analog signal control because of their low offset and high linearity.
The PS7122AL-1B, -2B have a surface mount type lead.
