Hi Hieu,
Lakshmi is out of office today so I will respond here.
4 meters is quite far for most microphones. What microphone are you using?
By turning up the gain to 42dB, your noise will also increase by 42dB. Such a large amount of gain will bring the…
Part Number: TLV320ADC6140 Tool/software: If the ADC6140 function is not used and SHDNZ= Low(power supply = 3.3V), will the ADC6140 open the I2C bus? Or short to GND?
Part Number: TLV320ADC6140 Tool/software: Could someone please confirm a few pieces of my understanding for clock parameters for the TLV320ADC6140 in master mode?
1. Reading the application note "Configuring and Operating TLV320ADCx140 as Audio Bus Master…
Part Number: TLV320ADC6140 Tool/software: Hi, Can you elaborate on wiring 2 analog MEMS microphones with differential output to TLV320ADC6140 in Channel Summation mode? Should I simply connect the first microphone Differential Output (+) to both IN1P and…
Part Number: TLV320ADC6140 Hello TI team,
I am wondering if you could please provide some comments on my schematic for a client. We are using the ADC to mux 6 PDM microphones and 1 analog microphone. I also have a question about mixed signal filtering…
Part Number: TLV320ADC6140 Tool/software: Hi, Team
Our customer use TLV320ADC6140 in their project, and they meet some EMI issues.
after check, they found the issue maybe caused by the BCLK (BCLK fw is 24.576M Hz). the BCLK waveform shows t hat the BCLK…
Part Number: TLV320ADC6140 I need to know the TLV320ADC6140 modulator clock frequency. The datasheet specifies the output sample frequency (FSYNC), but I can't find any information on the modulator clock frequency. I need to know this to properly design…
Part Number: TLV320ADC6140 Other Parts Discussed in Thread: AM5728 , , PCM5122 , ADS8361 , TAD5212 , TAC5212 , TAA5212 Tool/software: For my application, I am using an AM5728 running Linux and want 2+ch audio at 16 bits in and out at a non-standard rate of,…
I feel very strange now, when I reset the chip, all the registers are in the default state, at this time I wake up the chip (set 0x02 register to 0x81), turn off all the power (set 0x75 to 0x00), open all the channels (set 0x73 register to 0xf0), power…
