PERFORMANCE CHARACTERISTICS

Notes: 9. Guaranteed by design and/or characterization.

10. The upper bandwidth limit is determined by the digital filter cut-off frequency.

11. Common mode voltage is defined as the mid-point of the differential signal.

12. Dynamic Range defined as 20 log [ (RMS full scale) / (RMS idle noise) ] where idle noise is measured

from a CS3301A / CS3302A amplifier terminated input at 1x gain.

13. Signal-dependent Noise defined as 20 log [ (RMS full scale) / (RMS signal noise) ] where signal noise

is measured by subtracting out the signal power at the fundamental and harmonic frequencies.

14. Tested with a 31.25 Hz sine wave at -1 dB amplitude.
