Hi,
I am working in a power rail noise generator for ICs. The idea is to use the LT1210 configured as a buffer (G=1) to drive an IC power rail that has a continuous consumption of around 100mA and a 100nF input capacitor (minimum). The LT1210 is powered at +/- 5V and the IC input voltage is around 1.2V. The idea is to use a function generator to generate a square signal (1MHz, 100mVpp) with an offset of 1.2V and power the IC like that (with the LT1210 in the middle) to do measurements on it.
I have been looking for many power AOs that could be used for that but I ended up that the best so far is the LT1210. I have still a bandwidth problem since the square input signal has more than 35MHz I have to filter it a bit. So my question is if some of you have experience implementing such a circuit and if the LT1210 is the most appropriate AO or if others with better BW could work for that application.
Thanks!
