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

hello,

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.

• ### LET threshold for AD8561S?

Is there any information out there for the LET threshold for the AD8561S? Thanks in advance...

• ### AD8561 offset voltage measurement

Hi Team,

The Vout is getting saturated on trying to determine the input offset voltage of AD8561 through below servo circuit. Thank you,

### Q

We intend to use it with hysteresis as recommended in the data sheet. We also
intend to connect
a 5KW pull-up resistor to +3.3V for 3V operation.
For that configuration :

1.      What will be VOH ? (in the data…
• ### AD8561 LATCH pin Logic threshold

Hi,

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…
