NOTES

1VREF = 10.0 V, (Conversion Rate (fs) = 83 kSPS, fIN = 1.0 kHz, VIN = –0.05 dB, Bandwidth = fs/2 unless otherwise indicated. All measurements referred to a 0 dB

(20 V p-p) input signal. Values are post-calibration.

2For other input amplitudes, refer to Figure 13.

3For other input ranges/voltages reference values see Figure 12.

4fa = 1008 Hz. fb = 1055 Hz. See Definition of Specifications section and Figure 15.
