Hi Team,

I am planning to use SSM2167 in one of our audio application project. I have some query regarding the part. Our input voltage at pin no 5 from mic is of 1mV rms. Is the mentioned part capable to identify this low voltage?

 If not can you please…

I'm designing a product using a couple of these preamps. I have them in a custom dev board now and for the most part things are fine. However, I've discovered that need all of the features of this device EXCEPT the noise gate. I understand the concept…

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…

We seem to be having issues with the SSM2167 pulses can be heard on the output.

I believe the end of the question SSM2167 Gate question, seems to hint at the same issue regarding "pumping noise".

The problem seems to occur on the triggers…

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…

I cannot make PCBs for MSOP devices so I bought some modules through Ali Baba. Several suppliers offer the same module. It works correctly with 1:1 compression but not with any other resistor value from Pin 8 to Vcc+ (3 V). It stays in 1:1 mode. For 10…

Hi,

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…

Hi,
When I referred the datasheet & evaluation board schematic, I saw a 500K pull-up resistor connected to the SHUTDOWN# pin(#3) of SSM2167.
Why such a large value resistor used?
Is there any special requirement?
Can we use a 10K or similar resistor?

Greetings.  I have an audio chain that uses a SSM2167 to provide compression and limiting.  My circuit works well until the input voltage exceeds the Rotation Point voltage (limit threshold).  After the input exceeds VRP and drops back to 0 V, the output…

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
