Part Number: TLV320ADC3140 Tool/software: Hi team
One of my customer wants to achieve low power mode by TLV320ADC3140.
In low power mode, 4 MICs will shout down to 1 MICs, they want to know how to config the register, and how can we confirm the configuration…
Part Number: TLV320ADC3140 Tool/software: We have previously checked the filter update sequence on ADC3140 in the following thread: e2e.ti.com/.../tlv320adc3140-dc-offset-on-i2s-data-out-when-biquad-dynamic-update
After implementing this and proceeding…
Part Number: TLV320ADC3140 Tool/software: Hi Team,
May customer are using the ADCx140EVM to test the analog mic and digital mic SNR performance. But the test result have big difference. Could you please help check which settings is wrong? Below is the…
Part Number: TLV320ADC3140 Tool/software: There is a Q&A regarding the PCM output of the delta-sigma (ΔΣ) ADC.
As stated on page 19 of the specifications, it mentions the pulse code modulation (PCM) data format.
Is it correct to understand…
Hi Hattori,
It is a linear PCM. Each data word is a fixed bit width that contains the two's complement value of the particular sample.
