MODULATOR CHARACTERISTICS
Notes: 13. The upper bandwidth limit is determined by the CS5378 digital filter cut-off frequency.
14. No signals operating from external power supplies should be applied to pins of the device prior to its
own supplies being established. Connecting any terminal to voltages greater than VA+ or less than VA-
may cause destructive latch-up.
15. Common mode voltage is defined as the mid-point of the differential signal.
16. Dynamic Range defined as 20 log [ (RMS full scale) / (RMS idle noise) ] where idle noise is measured
from a CS3301A/02A amplifier terminated input at 1x gain.
17. Signal Dependent Noise defined as 20 log [ (RMS full scale) / (RMS signal noise) ] where signal noise
is measured by subtracting the signal power at the fundamental and harmonic frequencies.
18. Tested with a 31.25 Hz sine wave at -1 dB amplitude.
19. Specification is for the parameter over the specified temperature range and is for the device only. It does
not include the effects of external components.
20. This specification applies to the effective offset voltage calculated from the output codes of the CS5378
digital filter following offset calibration and correction.
21. Offset calibration is performed in the CS5378 digital filter and includes the full-scale signal range.
