I have to buffering a signal, derived from an AD8226 INAMP, using an opamp like the ADA4638-1.
The INAMP is powered with +12V, while the opamp uses +3.3V because it's interfaced with an ADC that works in the range 0:3V.
in the following table…
I am looking for an op amp to signal condition a low frequency (<100Hz) temperature sensor. I need a high precision amplifier with good offset voltage and drift. What are the appropriate amplifiers that you recommend?
The OP177 came out in 1989; why are we spending any time on it?
I told you:
-- Adusting offset increases TCVos
-- Large adjustment range means the customer is using it for a system level adjust; this is poor practice.
The customer can do whatever…
I simulated the ada4638-1 in multisim and just a simple unit gain buffer connection. But the simulation result shows the offset voltage is as high as 126 uV when supply voltage is +-10V, which is quite different to the data sheet.
Can anyone help me…
For the LT1006, I think the ADA4638-1 is an excellent part as replacement. ADA4638-1 is a high voltage, high precision, and zero-drift amplifier with rail-to-rail output. It has lower input offset voltage and drift, lower offset current, and…
Actually, the SPICE of ADA4638 was modeled at typical values on Vsy=30V. With that information, I wonder how you implemented the model as what you have mentioned above. Could you share your schematic, simulations. and target application please…
I simulated your schematic diagram in Multisim and the output of ADA4638 with supply voltage of more than 5V shows a ramp waveform (triangular) that exceeds the expected output of 4.8V. I also tried adding the 100kohm resistor suggested…
ADI has so many available op amps in DIP but OP284/OP484 best suits all your requirements. OP184 can operate from 3V to 36V, is unity-gain stable, has rail-to-rail input and output, has an output current of +/-10mA and can operate in the industrial…
