CS3301A
6 DS757F1
ANALOG CHARACTERISTICS (CONT.)
Notes: 13. Ratio of input common mode amplitude vs. output differential mode amplitude for a perfectly matched
common mode input signal. Characterized with a 50 Hz, 500 mV
peak
common mode sine wave applied
to the analog inputs.
14. Output impedance characteristics are approximate and can vary up to ±30% depending on process
parameters.
