Hello Alan,
The LMH6552 Enable input pin thresholds are referenced to the V+ terminal. So, here are your input High and Low level thresholds:
Vs= +/-3.3V:
VH_Enable = 3.3V - 2V= 1.3V from ground (minimum).
VL_Enable = 3.3V - 3V = 0.3V from ground…
Hi Arvind,
Here are my responses:
Question : Also the -VEE voltage has some current flowing into the supply . I am not sure how does this figure into the power calculations ?.
Response: If you look at the Excel spreadsheet from before, you will…
Hi Steve,
One way you can do that would be to use the LMH6523 Variable Gain Amplifier (digital control) to control your square wave amplitude. Then, you could process your amplitude controlled square wave (at LMH6523 output) through a VCVS (voltage…
Hi Rak,
Unfortunately I do not have access to the open loop Bode plot of the LM7372 which is not included in the datasheet!
If it is any consolation, you can use TINA-TI to get a good feel for what the device model shows the response to be.
Here…
Hi Ronald, I see the following note within the THS3062 (and a similar one for the THS3122 as well) which probably excludes it as well for your application (high slew rate and repetitive waveform): "The THS3061 and THS3062 are not recommended for applications…
The TINA-TI SNR (dB when Scale, Linear is selected for y-axis) is the ratio of the RMS signal (specified in the Noise Analysis dialog box) to the total RMS input referred noise integrated over the entire Start Frequency to the Stop frequency or the x…
Hi Abhi,
Here is one way to predict the isolation resistor OPA2690 needs for a given cap load using TINA-TI simulation.
I've used the OPA2690 model in simulation and used a large L and large C to open the loop and look for phase margin.
For the…
