Part Number: OPA1678 Other Parts Discussed in Thread: OPA1637 , LM27762 Hi Teams,
Since I am not familiar with ECM JFET circuit, and there is not ECM microphone component in TINA, I decided use traditional OP amplifier design to meet my requirement…
Hello Roger,
Upon inspection of your OPA1678 filter/amplifier circuit I do not see anything about the design that would explain the huge decrease in the gain. It would seem if the OPA1678 op amps had a problem that they would have stopped functioning…
Part Number: OPA1678 Hello Support teams,
There are some difference for OPA1678IDR in X-RAY analysis,d/c all within 2YRS,
I attached 2 picture below,and i have question here.pls help,thanks
1.why does it have two different result?
Part Number: OPA1678 Other Parts Discussed in Thread: TINA-TI I believe this needs to be approached as kind of a "power management" question, I don't think you have high-voltage power BJTs in your product line but I'm sure there's familiarity with this…
Part Number: OPA1678 Other Parts Discussed in Thread: OPA1652 , OPA1656
Hello,
Looking for a better alternative to replace OPA1678 which could provide higher gain when using it with low impedance input without changing the OPAMP packaging (VSSOP)…
Part Number: OPA1678 I do it as your method,but it can't settle for our function.
Your answer as follows :
"add a power supply decoupling cap to U2, replace L5 and L2 by a short circuit and remove the short circuit between the output of circuit…
Part Number: OPA1678 We have used OPA 1678 For microphone ,we want to the Frequency Response as attachment {Frequency Response of OPA 1678 }.But the actual Frequency Response as attchment {The actual Frequency Response }. Our schematic diagram as attachment…
Hi,
add a power supply decoupling cap to U2, replace L5 and L2 by a short circuit and remove the short circuit between the output of circuit and VCC. Remove C6 and replace it by a resistance.
What role plays R6 in your circuit? This resistance is…
Part Number: OPA1678 We have used the opa1678 for Automobile audio, we want the Frequency Response as the attachment {Frequency Response of OPA 1678 }，but the actual Frequency Response as hte attachment {The actual Frequency Response }.We dont know 3005…
Part Number: OPA1678 Hi Team,
Good day.
My customer is looking for the Output Current at 1V drop. We are looking in the datasheet and couldn't find this information.
Regards, Renan
