(a) Tested without an external load connected (1 nF output impedance only). Adding a capacitive load, such as a piezo, will decrease the noise because the capacitance will create a low-pass filter with the output resistance.

(b) The smallest allowable terminating resistance. Applying lower impedances will cause the short-circuit protection to limit the output voltage. Continued use in this mode will cause circuit degradation and eventual circuit failure.

(c) Assume a ramp function is used. The bandwidth depends upon the load and requires a calculation for a more representative number. See Chapter 6 of the manual for details.
