Hello,I need to build a sequencer for by the guidelines below..
Given that i have +-12V voltage supply.
questions:
1.What DC-DC do you reccomend me to use to get the +5V needed for the amplifier?
2.given that i control the system with microcontroller , what is the best wat to measure the current going threw the amplifier and control the Vg1 accordingly?
Thanks.

@yef smith How many times are you going to post the same thread? I, and several others, have shown you how to do this in varying level of detail... I even did a full circuit for you with an MCU controlled VG1 to meet the required IDD drain current. Of course you didn't give the full facts that you wanted to bounce VDD up and down at 1 MHz frequency for some as yet undisclosed reason, which will have an impact on the current sensing of IDD. Do you still need to do that?

 

Sorry Irving , yes I will continue at the previous post .
