I want cable driver for YPrPb output using ADA4891-3W.
Plz help me.
According to the product owner, both the storage temp range and Tjmax of ADA4891-1WARJZ-R7 are the same with the rest of the ADA4891.
Please see attached file for the SPICE model of ADA4891-3. Please note that this is just a probationary model, but it is a working one. Should you have questions or concerns, just let me know.
Customer wants HD video buffer amp with AEC-Q100 qualified part for ADV7393 output(YPbPr, 720p).
I thinks 3x ADA4891-1W or 1x ADA4891-4W is acceptable to cover 30Mhz video signal.
What is your opinion? If it is not OK. Please suggest right parts…
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 AC_SHIELD output is 250kHz, so the buffer does not need to be particularly wide band.
I'd recommend the ADA4891 op amp, its available in a SOT23 , and has the required slew rate and low input capacitance.
how to reduce peaking in op-amps eg. ADA4891-1, at the high frequency
可以参考一下ADA4895-1 或者 ADA4897-1 ADA4800 ADA4891-1
