What is the SNR of a 16 bit ADC?
16-bit, 160Msps ADC Delivers 77dB SNR for High Performance Communications Systems & Instrumentation.
How do you calculate ADC SNR?
Signal-to-Noise Ratio
The ideal theoretical SNR is calculated directly from the resolution (N bit) as SNR = (6.02 × N + 1.76)dB. However, for delta-sigma ADCs like the MAX11216, which features internal programmable low-pass digital filters, the SNR can be increased by adjusting the amount of filtering.
What does the ADC SNR mean?
ADC Signal-to-Noise Ratio (SNR) If an Alternate Current (AC) signal is applied to an ideal Analog-to-Digital Converter (ADC), noise present in the digitized output will be due to quantization error. For the ideal converter, the maximum error for any given input will be +/- ½ Least Significant Bit (LSB).
What is the relation between signal-to-noise ratio and bit depth?
The bit depth limits the signal-to-noise ratio (SNR) of the reconstructed signal to a maximum level determined by quantization error. The bit depth has no impact on the frequency response, which is constrained by the sample rate.
