Dear Respected,
We are planning to use SSM2167 in one of our project.
Where output of MIC is connected to input of SSM2167 and output of SSM2167 is connected to Audio codec, we have tested with external setup by soldering this IC in general purpose…
Hello Sayantan,
The SSM2167 is not a microphone preamplifier, it is for conditioning a microphone signal so it has some gain to be able to adjust the dynamic range of the signal but not enough to actually work as a preamplifier.
You did not mention what…
Hi,
We are looking at using the ADA4075-2 instead of the OP275, as recommended by ADI, as a balanced line driver to the AD1974. However, the reference design uses trimpots whereas these are not shown for the OP275 reference design. As we are looking…
We are using ssm2167 Pre amplifier IC we are able get good amplification but receiving huge noise.
Please revert ASAP how can we reduce this noise
I was connecting Wolfson MEMS microphone to the EZ-Kit 561 via an elval board SSM2167 and output the data to small speaker via SSM2303 eval board.
all of them stopped to work. I've use all electrostatic precautions (glove and wrist to the ground…
Hello vishnu_riosh,
I do not think you can directly connect a microphone to the ADC of ADAU1701, reading the datasheet, these are line inputs.
I think first you have to preamp the microphone signal for example with an SSM2167.Then maybe Dave has a better…
Hello Schertler,
In case you have a My analog account you can check this link, the document discusses an application that uses OP484 as an integrated mic preamp and amplifier driver.
