• QML Qualified per MIL-PRF-38535 Requirements
• Radiation Environment
important feature; they withstand analog input voltages much
greater than the supplies. This is essential in any system where
the analog inputs originate outside the equipment. They can
withstand a continuous input up to 10V greater than either
supply, which eliminates the possibility of damage when
supplies are off, but input signals are present. Equally
important, they can withstand brief input transient spikes of
several hundred volts; which otherwise would require complex
external protection networks. Necessarily, ON resistance is
somewhat higher than similar unprotected devices, but very low
leakage current combine to produce low errors. Reference
