AD8561 Latch function not working in simulation. I'm simulating a circuit using the AD8561 and not able to get the latch function to work. I set up a simple test circuit with 5V pwr and GND (a single supply circuit). I put a reference voltage on one…
Need Reliability data for AD8561 or good estimate
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...
The Vout is getting saturated on trying to determine the input offset voltage of AD8561 through below servo circuit.
Please help to confirm whether this approach is good to proceed and also please provide your suggestion.
I'm looking at the LATCH pin in AD8561.
It seems like LATCH logic threshold values are strange.
For example, LATCH pin Logic "0" (TYP) should be less than (MAX).
But, Datasheet shows (TYP)=1.6V, (Max) = 0.8V
Could anyone explain…
请问ADI工程师 ，AD8561电源电压极限值为多少呢 ？
I've been using the ad8561 in the following circuit:
IN- connected to OUT- via few resistors (hystersis of few tens of mV) around 0V.
IN+ gets a sine wave signal with frequencies as low as 100Hz. When crossing the 0V point, the output toggles…
