Part Number: OPA828 Other Parts Discussed in Thread: TINA-TI Tool/software: I have built the circuitry shown below, which is a 1 MHz amplifier capable of driving at 150 ohm load with up to +20 V. When loaded with too high capacitance (a 2 m RG58 coax…
Part Number: OPA828 Other Parts Discussed in Thread: OPA827 , OPA810 , OPA1656 , UA741 , OPA596 , OPA593 , LM4040 , OPA197 , OPA192 Tool/software: Dear Support Team,
We are trying to verify the behavior of a supply-bootstrapped circuit using OPA828…
Part Number: OPA828 Other Parts Discussed in Thread: OPA1641 ,
I went through the OPA828 datasheet and could not find anything regarding stable input capacitance like there is for the OPA1641. Do you know if the JFETS were built using the DI process…
Part Number: OPA828 Other Parts Discussed in Thread: LF356 , Asking on behalf of customer.
According to first page of datasheet, input bias is 10x different DGN package vs. D package.
What is driving this discrepancy?
Contact me internally if further…
Part Number: OPA828 Other Parts Discussed in Thread: OPA627 , OPA140 , OPA2828 , OPA827 Hello,
We have legacy TIA for photodiode that was using OPA627. TI lists OPA828 as being a "drop-in" replacement for it however after just swapping OPA627 to OPA828…
Part Number: OPA828
This seems to be a new plot, can't make much sense out of it, does the Aol polarity really change across temperature - surely not,
Being bounded by 0.1uV/V, I am interpeting this as the inverse of the DC Aol and it implies…
Part Number: OPA828 Hi,
Let me ask you some basic questions about input impedance.
There describes the value in the datasheet 5 page, 1Tohm.
Q1) What is the meaning of "Differential"(ZID) and "common"(ZICM)?
Q2) How do you measure the value? …

Part Number: OPA828 Hi team,
I couldn't find the phrase of "unity-gain stable" in the datasheet.
This means we need to add some caps for unity gain purpose?
From Fig22, it looks to have enough phase margin, though.
Let me clarify if we need…
Hi Marian,
I am using LTSpice and your Spice model. Could you advice how to correct this model?
I do not see issues with OPAx828.LIB that I downloaded from the following website.
