OP184: Offset nulling pins

analog-archivist

Q
The OP184 has two offest nulling pins. What resistance should the nulling
potentiometer have, and where is its slider to be connected to?

A
For offset adjust, use a 20K resistor between offset null pins 1 and 5 with the
wiper to the negative…

OP184 offset null pins

analog-archivist

Q
We need OP184 or similar device which has still the NULL pins for offset
adjustment (so we don’t need the latest auto zero parts). Does OP184 have this
feature? Because pin1 and pin5 on page 1 of the former datasheets shows them,
but…

ADF4108 loop filter design: using OP27

Guruditya

We are trying to use the schematic provided in UG-160 (ADF4108) eval board user manual.

Can we replace the OP184, which uses a single rail 15V supply, with an OP27, which uses a dual rail +/-15V supply.

Can we avoid using the -15V supply rail and ground…

OP184: Replacement with the AD820 and NULL Pin

analog-archivist

Q
Is it possible to replace the op AD820 with the op OP184? What means the pin
connection NULL?

A
The OP184 and AD820 share a similar pin out but they vary significantly in
their bandwidth, offset, and noise. I would not consider them to…

OP184: Hot to implement a trim circuit

analog-archivist

Q
How to implement a trim circuit on the OP184 - not described in the datasheet!

A
The Null function on the OP184 is used to trim the input offset voltage. It is
an optional function. If you are not going to use the offset nulling circuit …

RE: How to decrease noise of amplifier?

FormerMember

ADA4084-1 is next generation OP184; higher speed, less power, less money.

HI Anna：

thank you for your answer，

But I've added the REF pin a voltage（2.5V） by op184，Is this not a right way？

how should I set？
