Part Number: OPA1678 Hello Here is my concern on these parts. I see pictures of these parts online and on the data sheet and they don’t show the mold pin cavity, only the bar on the left. In addition, the top marks are in varied locations on the tops…
Part Number: OPA1678 Other Parts Discussed in Thread: TINA-TI hi, team
our customer using OPA1678 in their smart speaker, they they prefer to know the measure method of our PSRR and CMRR.
Could u help to give some suggestions?
Thanks.

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…

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…
