Electrical characteristics

Every parameter in this chapter is fulfilled down to VINGOOD(max).

No device damage is granted to occur down to VINBAD(min).

GNDA pin is used as ground reference for the voltage measurements performed within the

device, unless otherwise stated.

All table or parameter declared "Design Info" are not tested during production testing
