In AD8629 Spice model the Flicker noise parameters and Noise models such as the ones mentioned in AD8617 SPICE model has not been given in AD8629 Spice model. Hence i here by request you to kindly provide the AD8629 SPICE model with all the noise parameters…
First, let me tell you I am biased, and think that typicals are a waste of ink. Over the past 35+ years,
I have seen a lot of people get in trouble with them. What is a typical? Is it an average? a mean?
On how many parts? One lot from five…
There are no plans at the current time to perform any further TID testing on the AD8629S.
hi dante2608: the CN0338 use the HTS-E21-F3.91/F4.26 thermopile sensor made by HEIMANN, this sensor have typical 37nV/sqrt(Hz) voltage noise density, the AD8629 have 22nV/sqrt(Hz) input voltage noise density and 500nVpp 0.1Hz~10Hz input voltage noise…
Did you resolve the AD8629 offset issue? We have found a similar problem when using the AD8629 in a thermopile amplifier: the offset changes after cycling the power to the circuit. We use 2 identical amplifier circuits in a thermopile based gas detection…
Our customer found the following matter with your AD8629 OPAMP.
Application is temperature sensor by Thermopile(TP).
Please refer to my enclosed Fig-1 schematic.
In the enclosed schematic, customer replaced TP to fixed resister.17…
Autozero op amps are not continuous time circuits. See MT-055 and MS-2062.
There have been four generations of AZ op amps, so some handle fast changes better
than others. Suggest you breadboard. BTW, the Spice models are continuous time
so they are…
