Other Parts Discussed in Thread: TLV320AIC3263, TLV320AIC3262, TLV320AIC3007
Hello,
My customer needs the following requirements and I'd like to propose TLV320AIC3107, TLV320AIC3262 or TLV320AIC3263, but the most important item is against wind noise. I think it can be done by biquad filter for TLV320AIC3107 and miniDSP for TLV320AIC3262/63.
- Requirements
- MIC inputs by 2-ch analog single-ended(stereo microphone 1-ch)
- MICBIAS 1ch(1.5V ~ 3.6V)
- CODEC with 16~24bits
- ADC/DAC SNR is don't care
- Fs=48kHz
- Wind noise prevention by digital HPF
- Speaker output(8Ω) of 1-ch
- Small package
- Audio interface of I2S
- I2C Control(or SPI)
- Samples in TI.com inventory are available
- Proposed Devices
- TLV320AIC3107 by biquad HPF(no sample of TLV320AIC3007 now, so TLV320AIC3107 will be proposed)
- TLV320AIC3262 by miniDSP
- TLV320AIC3263 by miniDSP if only mono is required
- Questions
- Do you think my proposal is appropriate?
- Would you please tell me the advantages/disadvantages of both biquad and miniDSP?
- Would you please provide me frequency response of each biquad and miniDSP so that my customer can decide which one will work well on their system before asking samples?
- Would you please provide me materials of designing HPF by biquad or miniDSP for wind noise?
Best Regards,
Yoshikazu Kawasaki
