Hello dear TI community.
I've got rahter simple question about enable pin of OPA1622 amplifier.
I'll use demux 2:1 IC to switch enable signal between pairs of OPA1622 in my design.
I picked SN74LVC1G18 for this job - input of this demux will be always high state (input will be feeded by voltage supervisor and let's consider that voltages will be within range // supervisor output will be pulled up to 5VDC).
Because I want to avoid relays etc. my question is did I picked right solution or maybe I should consider different approach?
Another question is if I turn up one OPA1622 with high state signal, does high-impedance OFF-state will turn it off?
Is it safe to use high-impedance OFF-state to turn off that kind of chip?
Or maybe I should add some pull down resistor to that signal in case when it will be high impedance state?
Thank you for helping me.
Have a nice day.
