Part Number: OPA365
Other Parts Discussed in Thread: REF4132,

Hi,

I'd like to use series voltage references (REF4132) to supply the OP amps.

The maximum output current of REF4132 is 10mA.

Is it enough to supply the three Op amp of the circuit below.

The Op amp is OPA365.

Thanks.

Hi Eric,

the supply current of each OPA365 is up to 5mA (without load), which makes 15mA for all three OPA365 :-(

Hello Eric,

As Kai said, you would not be able to use the REF4132 to supply three OPA365 (quiescent current is 5mA). Would up be open to changing the REF4132 or your amplifiers?

Thank you,

Sima
