Can you assist with emulation or calculator software references for the above design
I have the quad pack chip AD 6828
I will adjust CMRR in the lab as component excursions
The low offset current and voltage corrections need to Bec solved simultaneously and the pin connects to replace the null offset pins on general purpose of amps means I need a circuit component calculator that understands a model where it all hangs off the I o pins. Can you advise on a circuit value calculator to determine all component values for a specified offset current and voltage. An a positive and negative pair of LDO VOLTAGE REFS.
The layout on a board is the next challenge any notes or text references to where and how short leads on components should be would be appreciated
Then what pots and trim caps can be added and where to compensate for thermocouple effects of leads solder and track copper
And finally what test circuit board and gain I should use to get a precise offset voltage and current offset to match my quad pack chip
Then again is there an evaluation voltage follower board to do it all for me and all I do is plug in the test values for a specific low noise quad op amp
Over to you
Can you please check the part number because AD6828 is not included in the ADI amplifier portfolio. On the other hand, you can use ADA4505-4 or AD8508 which are low noise RRIO Quad Op Amps with zero input crossover distortion and have a typical CMRR of 105dB.
Regarding the evaluation board, you may use ADI's Quad Precision Op Amp Evaluation Board wherein you can test the suggested parts.
