ADG451/ADG453(IN1~IN4) how can control is very energy efficient?ADG451 datasheet Rev.C Page4 "DIGITAL INPUTS" tell me VINH=2.4V, VINL=0.8V, IINL=0.005uA, IINH=0.5uA. If MCU GPIO need control IN1~IN4 arbitrarily pull-up or pull-down. R1=6.6M…
My customer uses ADG453BRZ-REEL7, but they can confirm 2 type of top silk on ADG453.
One is ADG453BRZ and others are ADGBR on Top.
But as on the reel, boths are ADG453BRZ devices.
Q1) Would you confirm contents in pictures on top of device…
My customer uses ADG453 supplying +12V (DP12V) at VDD and -12V (DN12V) at Vss like below schematic.
And when -12V trip out, L2 is damaged and ADG453 become hot.
At this time, current of L2 is 1.25A. (At normal operation, current of L2 is 0.08A…
