Part Number: OPA820-HT Other Parts Discussed in Thread: OPA820 In the datasheet for the OPA820-HT the input and output voltage ranges for the amplifier at Vs=5V (see pg.7) are specified as an absolute amount of 3.2V*, without any reference to the supply…
Part Number: OPA820 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Hello there,
both the SPICE and the TINA-TI Models for the OPA820 have wrong input currents. Approx. 14uA flow into the inverting input, whereas only 7uA…
Other Parts Discussed in Thread: OPA820 Hi,
The datasheet for OPA820 gives noise curves only to 10 MHz although the part has gain out to several hundred MHz. Does the noise remain flat above 10 MHz? Using the PSpice model I seem to see the noise rising…
Hi William,
The typical numbers were based on measuring a lot of parts. It would be best to use the +3.8V typical number. The parameters of the output devices will change from lot to lot so the exact voltage will be different for different parts. …
Thanks for your feedback.
The OPA656U was used in a previous working design, I agree the OPA820 is a much better part.
I have a working design / layout so did not want to change the design from SO-8. I will have a look at the OPA820.
I am keen to keep to MSL…
Part Number: LMH6601 Other Parts Discussed in Thread: LMH6611 , OPA820 , OPA692 , OPA693 , LMH6704 Hi Team, My customer is looking for a video amplifier that supports the following signal. - NTSC - PAL - Tri-level Sync (HD) Does LMH6601 support above? Best Regards…

Hi,
The excellent op am OPA820 is used as an error amplifier in an LDO circuitry, shown as above.
OPA820 is suppled by only the +5v single supply. the LDO input is 3v3, and the output is setted as 3v0.The pass…
Part Number: TL084H Other Parts Discussed in Thread: OPA820 , OPA810 , MUX508 , , OPA1644 , OPA4141 , OPA2145 Hi,
I'm asking myself if there are J-FETs in the Input stage (for true MUX Friendly operation) or MOS transistors with some kind of gate protection…
Michael Steffes said: You may have said already, but what is the BP target? Fo =10MHz I suppose, but Q
I followed the detailed design procedure in the OPA820 for the high Q filter (section 10.2.1.2.1)
Input parameters were Fo= 1.5MHz and Q = 10.
We can…
