1 The MDT693B and MDT694B were tested without an external load connected (1 nF output
impedance only). Adding a capacitive load, such as a piezo, will decrease the noise spec since the
capacitance will create a low-pass filter with the output resistance.
2 The Min Load Impedance represents 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.

Assume a ramp function is used. The bandwidth is load-dependent and requires calculation for a
more representative number. See Chapter 6, page13 for details.
