Part Number: OPA828 Tool/software: When operating with +15v and gnd as the supplies to the op-amp, how close to zero volts can the output drive? (load < 1mA) ?
Does operating close to the negative rail (ground) reduce the op-amp precision (drift, offset…
Part Number: OPA828 Tool/software: Hello,
I'm working on a TIA circuit to detect 100pA current, and bandwidth need to be around 15kHz. The current is generated by a voltage buffer on the PCB and a 10G resistor connected by coaxial wire.
And I found…

Hello,
I find my TIA output is not correct.
And when I remove the input (so nothing connect to RF1), the output should be near zero. But one of my boards…
Part Number: OPA828 Tool/software: Hi,
I am simulating Howland charge pump with OPA828. I see the edges are getting chipped off in my output. Any idea on why this could happen?
Thanks,
The input rise time is 10uS and 5V at 100Hz.
Part Number: OPA828 Other Parts Discussed in Thread: OPA192 , Tool/software: Hello team,
My customer is evaluating OPA828. The electrostatic discharge of OP828 is ±2000V. But some opamp (ex OPA192) cases are ±4000V.
Is this due to the difference…
Part Number: OPA828 Kind of scanning through the OPA828 datasheet (2022 update) this plot
So that Aol over temp plot should say 1/Aol and I really doubt it flips polarity over temp
Part Number: OPA828 Other Parts Discussed in Thread: OPA827 , Tool/software: I'm using the OPA828 as a preamp for a reproduce head in an analog magnetic tape recorder. This is the first time I've tried using a FET-input opamp for this job, because opamps…
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…

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…
