Quiz: How Well Do You Know Adaptive Power Switching?
Is your I/O module overheating? The AD74416H's Adaptive Power Switching (APS) can cut heat dissipation by up to 40% — but how well do you really understand how it works?

Hi
According to LTC2249 datasheet for the ±1v mode (V sense connect to Vdd), is the ADC's full scale range 7dBm for a 100-ohm input impedance ?
Due to a 73dB SNR is the minimum input power level of ADC -66dBm?
Best regard
Hi jessi,
Thanks for your interest in LTC2249.
According to LTC2249 datasheet for the ±1v mode (V sense connect to Vdd), is the ADC's full scale range 7dBm for a 100-ohm input impedance ?
Yes, this is correct. The ADC full-scale swing is 2Vpp and is equivalent to 6.9897dBm for 100-ohm input impedance.
Due to a 73dB SNR is the minimum input power level of ADC -66dBm?
No. The SNR parameter is in dBFS scale, and not should be interpreted in dBm. SNR (dBFS) = Signal (dBFS) - Noise (dBFS)
As for the 73dBFS SNR, the analog signal is -1dBFS as per test conditions.
Regards,
Xavier
