I have specific reason to simulate the circuit in the SIMPLIS simulator, could you please provide the SIMPLIS model? The SPICE model on the website is not compatible with the SIMPLIS.

I have designed multiple filter configurations using the LT1568 on a custom board. When I try to power them, I get excessive current draw, saturating the regulator. So it looks like the IC is short circuiting somehow. I have followed the design guide...

Hi Analog Team, I like to have a second opinion on the impelentation of an ADC driver we need to build in. In a current design, we are using an VGA (AD8336ACPZ-R7) that is directly connected to an ADC (LT2249) input. Well, lessons learned, we are unable...

I came across this design - AD8138 driving an ADC with variable gain. The gain is set by pairs of dip switches in the feedback loop. Is this acceptable from a stability standpoint? I always assumed the NFB loop needed to be as tight as possible on high...
