I want to build a composite amplifier using the Figure 77 of the datasheet ADA4870-1. It says that the voltage offset is less than 500 uV. I simulate this circuit using LTSpice, when driving ada4637-1 with 0V and monitor the output of ADA4870-1, it is…
My question is concerning the ADAS1000-1. There are certain electrode input ranges usually from 0.3V to 1.6V I believe. Does that mean we would need to implement an amplifier before sending the ECG signal to the ADAS? Just because an ECG signal…
Thanks for providing the spice model of both ADA4433-1 and the ADA4830(-1).
I'm trying to design a DC coupled differential transmission system using the ADA4433-1 and the ADA4830.
The overall gain from input (ADA4433-1) to output (ADA4830…
When using 4310-1 or 4311-1, with PD0 and PD1 pins taking values between 0V and whatever is considered logic high, does the amplifier behave reasonably? By that does it behave without going unstable or draining excessive current or requiring excessive…
It’s a new beginning for Analog Devices and Linear Technology. Together we become the high-performance analog industry leader with an innovation engine fueled by our comprehensive portfolio of analog and mixed signal products and solutions.
The supply pins you mentioned above are still connected internally to the supplies of the ADATE305. They should still be shorted to VDD and VSS respectively. The reason for their special mention on the datasheet was so the user can pay special…
What is the difference between the ADA4940-1 and the ADA4941-1? They are both ADC drivers, but what distinguishes the two parts from each other?
ADA4627-1 and ADA4637-1 have NULL pins which are offset adjust pins. If I do not plan to use offset adjust what should I do with the NULL pins? Leave it floating or use 100k Ohm pull-up resistors?
1:1 transformer applied in IF pin is expensive.
so we want to use without transformer.
is it possible that?
Can you support solutions?
Is there any documentation for the evaluation board for the AD8195?
