Dear TI teams,
For our customer's application: We use the MCU (STM32) and codec IC (TLV320AIC3256). We found the confuse about extra gain here.
We use the label mic, and its spec…
Part Number: TLV320AIC3256 Hi,
We're trying to get the AIC3256 running in a new design and have an issue where it seems like the miniDSP's are not running.
Reading/writing over I2C to load the codec seems to be working fine.
VSYS, IOVDD = 3.01v…
Part Number: TLV320AIC3256 Other than a simple HPF, is there an algorithm available from TI (either in PurePath Studio or elsewhere) that can be implemented in the miniDSP to remove microphone wind noise from a 2-mic input configuration?
Part Number: TLV320AIC3256 We are having difficulties in achieving unipolar configuration for headset connection and associated MICBIAS of 2.5V
Below are the configurations we have done to set the MICBIAS:
The coefficients can be calculated on the fly, the coefficient calculator isn't doing anything special, it uses the calculations that are described in the document I linked to.
can you explain where your calculations are going wrong?
Part Number: TLV320AIC3256
I am using the Biquad Filter Design Tool in the PurePath Studio. I choosed the Equalizer(Q factor) filter. Then I set the Fc, Gain, Q as shown in Fig.1
Applying the equations in section 1.2 of Biquad Filters Application…
Part Number: TLV320AIC3256 Dear TI,
This is Derek from Arrow Asia. My customer application need below:
1.Double-mic input, d ouble-horn output, and mic need match horn one by one.
2.Need AEC function
I have recommended AIC3256 to my customer…
Part Number: TLV320AIC3256 Dear Sir/Madam
In the datasheet http://www.ti.com/lit/ds/symlink/tlv320aic3256.pdf the ball D5 is not mentioned.
Can you recomend a connection for this ball - e.g. "connect to gnd" or "leave floating" ?
