I'm using the ADA4891-1 in a non inverting application - With amplification of 2.
I'm using VS=3.3V , RG&RF = 604 Ohm, Input resistor-Rt=200 Ohm, I have 100n and 10u Capacitors betweren Vs and Gnd, Input Voltage=1V, output Voltage=Ringing!!…
I was wondering if the ADA4891-1 can be used as a unity gain buffer? I have a unity gain stable amp on my PCA already but for consolidation of parts and for operating temperature range, I would like use an existing amp I have on my board, the ADA4891-1…
I would like to use ADA4891.
So, I simulated using LTSpice, but the + side of the output voltage will saturate halfway.
This IC should be a product of Rail to Rail.Is the contents of this model correct?
Currently i am doing a test PCB in order to simulate a wide range of thermistors sensors. I generate a voltage with a DAC (TLV5630) and then jus to protect the DAC i use a amplifier as votlage follower.
First of all i used AD8548, but I found with…
We are using ADA4891 for sample and hold circuit , but would like to know if the Amplifier be stable when the capacitor drains of the
charge leaving the input similar to that of Floating state.
We are using a switch before the capacitor connected…
The recommended schematic for non-inverting gain has positive and negative power rails on the op-amp. The reason for this with the op--amp VSS tied to ground , the op-amp will have problems driving the output signal to ground. The reference schematic…
ADA4891-1W schematic review at ADV7393 DAC output by Steven.firstname.lastname@example.org
As we discussed, customer would like to apply video buffer amp for 720p YPbPr at ADV7393 output.
I draw the schematic and the configuration as well in attached file.
Is storage temperature of ADA4891-1WARJZ-R7 (Qualified for Automotive Applications) −65°C to +125°C ?
Is Tjmax 125°C ( or 150°C ) ?
Is the ADA4891-2 a good candidate to create a SE to Diff amplifier to be used as amplification stage of piezo sensor?
I'd like to simulate a circuit using the output disable capability of ADA4891-3, but I couldn't find a spice model which includes the output disable pins. Is there one available?
If so, how can I download it? Can I use it with LTspice?
