Hi,
I need a clarification regarding the Rail to Rail amplifier AD8051.
We have used the amplifier AD8051 in our design & we have connected the amplifier as shown in the below image.
We are receiving 200mV output offset voltage without connecting any inputs & after connecting the input terminals with ground too, what may be reason for that output offset voltage(200mV)?
Hi Gokulram,
On your first condition is the input left floating?
Can you try turning on the device with the input on a known linear input level.
Also, I'd like to know how you measure the device and what are you using in measuring.
Regards,
Goz
1. We have short the input terminal(+IN) with ground.
2. We have tested the device with the known linear input -2.4V applied in the non inverting terminal, then we have got the output as -2.55V
3. We are measuring the output of the op-amp using digital multi meter(6th pin of the device with respect to ground).
Hi Gokulram,
I don't see anything wrong with the methods and configuration of your circuit that will result to such offset.
Are you using an evaluation board or are you using a customized pcb of your own? If customized can you share the layout file?
How many units are you observing with this behavior?
