Need Reliability data for AD8561 or good estimate
A few questions for you:
- What are the supply voltages for the AD623 and AD8561?
- What is the AD623 reference voltage?
- What is the gain of the AD623?
- Can you elaborate on "this seems to cause problems with the AD623".…
In the AD8561 datasheet, page 8, a hysteresis circuit is shown:
The capacitor CF is added to introduce a pole into the feedback network.
The calculation for this pole is:
Is this formula correct? In the formula, I would use R1 instead of R2.
Is there any information out there for the LET threshold for the AD8561S? Thanks in advance...
Do the oscillations occur when the inputs are near zero cross? That could actually be a noise problem rather than an oscillation, and might be fixed with a little more hysteresis.
The LT1711 is quite a bit faster than AD8561. The LT1713 is…
Hi, I have a question about using AD8561 for 100kHz or higher frequency Sine to Square Wave Conversion.
The comparator I'm using is AD8561 and the circuit diagram I set up on breadboard is
And the response I get is as follows, with sine wave…
