Part Number: TIPD181 Thank you for the circuit design.
However, Would it be possible to provide a design with somewhat larger components?
This one uses 603, which is pretty small.
If you look at the overall PCB size and complexity, there is no logical…
Part Number: TIPD181 Other Parts Discussed in Thread: OPA172 , TINA-TI Hi Team,
I want to rebuild the TIPD181 pre-amplifier. My first step was to order the TIDC916 PCB from JLCPCB. Then I assembled all parts from the TIPD181 reference design guide .
I applied…
Part Number: TIPD181 Hello,
I am looking to compare the mag of frequencies between 35 and 250hz captured from an electret condenser microphone. I would like to use this reference design to get started but noticed a roll off in the transfer function around…
Lifang,
Is this the design? http://www.ti.com/tool/TIPD181
Are two of these circuits in series (output of one connected to the input of the other)?
Is the noise on the headphone just plugged in or is the noise heard somewhere else?
Hi Arash,

Hello Wenting,
Absolutely! The OPA1692 datasheet has an example of a preamplifier for a 3-wire electret microphone. Please refer to page 24 of the datasheet for an explanation of this: http://www.ti.com/lit/ds/symlink/opa1692.pdf
We also have some other…

Thanks
Hi Andreas,
I have a bit analyzed the circuit of the www.ti.com/.../TIPD181.
It seems that this circuit does not allow any cabling at the input because the microphone line directly connects to the -input of OPAmp. Any cable capacitance would erode the…
