Quiz: How Well Do You Know Adaptive Power Switching?
Is your I/O module overheating? The AD74416H's Adaptive Power Switching (APS) can cut heat dissipation by up to 40% — but how well do you really understand how it works?

ADG751
Production
The ADG751 is a low voltage SPST (single pole, single throw) switch. It is constructed in a T-switch configuration, which results in excellent Off Isolation...
ADG751 on Analog.com
Hello,
I want to use ADG751 switches for a circuit I am working on. My switches in this circuit are floating (sources are not grounded), will be this a problem using ADG751 CMOS switches? Also, I am driving the gate(switch on and off in high speed around 1MHz) using a microcontroller, do I need to have an isolation for the floating source? or I need a bootstrap circuit to ensure turning the switches on & off ?
Thanks
Jacob
Hi Jacob,
The signal presented to the source/drain of the ADG751 needs to be between -0.3V and VDD + 0.3V so that the absolute max ratings are not violated. The absolute max ratings are referenced to the GND of the device so if the voltage source is floating you would need to be able to guarantee that the input voltage max range is not violated.
The digital logic input high and input low voltages are also referenced to the GND of the device so the logic input signal needs to be 2.4V above the device GND for the switch to turn on.
Regards,
Stephen
