1 Includes amplifier voltage and current noise, as well as noise of internal resistors.
2 dBu = 20 log(V rms/0.7746).
3 Includes input bias and offset current errors.
4 May also be limited by absolute maximum input voltage or by the output swing. See the Absolute Maximum Ratings section and Figure 8 through Figure 11 for details.
5 Internal resistors are trimmed to be ratio matched but to have ±20% absolute accuracy.
6 Common mode is calculated by looking into both inputs. The common-mode impedance at only one input is 18 kΩ.
