Product Number: AD8062
Hi
I’m using AD8062 by voltage follower. Then I have confirmed Vout drop from 3V to 2V.
Could you confirm the following specification.
V+ : 3.3V
V- : GND
+IN : 3V
Rload : none

Hello,
Can you send me your circuit schematic for me to check?
Thanks.

Hello kshigemori281 ,
The input voltage range of AD8602 has a headroom of 1.8 V, meaning for it to work satisfactory, the input voltage should not exceed the Supply Voltage minus the headroom (Vs-headroom)
For example, for Vs = 5V, the input should not exceed +3.2 V
Max input voltage = Vs - headroom = 5V - 1.8V = 3.2V
In your schematic, using the above formula, the input voltage should not exceed 1.5 V for it to work satisfactory.
Max input voltage = Vs - headroom = 3.3V - 1.8V = 1.5V
As a recommendation, you can increase your supply voltage to 5V so the part can accept the 3V input and work as it intended to be.
