TDA9910
12-bit, up to 80 Msample/s, Analog-to-Digital Converter (ADC)
[8] Intermodulation measured relative to either tone with analog input frequencies fi1 and fi2. The two input signals have the same amplitude
and the total amplitude of both signals provides full-scale to the converter (−6 dB below full-scale for each input signal).
d3(IM3) is the ratio of the RMS value of either input tone to the RMS value of the worst case third order intermodulation product; d2(IM2) is
the ratio of the RMS value of either input tone to the RMS value of the worst case second order intermodulation product.

VIN(p-p) − VINN(p-p) = 1.9 V; VFSIN = VCCA1 − 1.77 V; typical values to AGND.
