5 Summary

In summary, every doubling of the number of ADCs used in parallel increases the dynamic range and SNR performance by approximately 3 dB. The TLV320ADC6140, TLV320ADC5140, TLV320ADC3140, TLV320ADC6120, TLV320ADC5120, and TLV320ADC3120 from Texas Instruments feature an in-built channel-summation feature. This application note details a method to increase the dynamic range and SNR performance of audio ADCs using this in-built channel-summation feature.
