The specs you mention should be sufficent with the additional need for Input Bias Current <= 100pA for electret mics. ADI has lousy packaging selections and Linear Tech is notoriously expensive (though good). National seems to be the best bet for 1.8V parts in small packages. I've got some...

I do not have any flexibility with respect to the inputs. I need to solve the problem as stated. The line and mic inputs are always simultaneously present and the CPU (embedded application) decides which pair are active at any given time, depending upon device state. I've solved the analog...

Hello everyone, I need to share the stereo line inputs to a codec with dual electret microphone inputs. My plan is to have a 2-channel analog switch under CPU control and feed Left Mic & Line to one channel and Right Mic and Line to the other. The Mic inputs would of course be fed through...

Thanks everyone for all the helpful replies. I'm going to go with the TT Electronics PWC series in a 1206 package for now. I'm more concerned with the H dimension than L & W so this will work fine for the current application. -Chris

Thanks everyone. After poking around the KOA Speer website a bit more I did find an App Note on the subject: http://www.koaspeer.com/pdfs/Thick_Film_Pulse_Limitation.pdf However, the time resolution on the graph only goes down to 10us, so I can't get a definitive answer from it directly. I...

Hello folks, I want to use a ceramic cap + series resistor in place of a single Tantalum cap for the load capacitance on a USB VBUS power input (end-point). I'm doing this for both cost and cap size (height) profile advantages. I'm planning on using a 1 ohm resistor in series with a 4.7uF...

Ahh... a band-aid in the works... thanks Bobby! Inductors and capacitors are pretty much the same thing when we get to GHz, huh. They could have gotten away cheaper though by using an inductor. Parasitic capacitance between the windings would discharge through L and solve the environmental...

Hello, I have a general question about EMC treatments for ground interfaces associated with high speed interfaces. I've seen the cat skinned several different ways for USB2.0 connectors and I'd like to get a better understanding of why these different approaches are taken. It would be nice if...
