ELECTRICAL CHARACTERISTICS (continued)
(V
Note 1: Specifications to -40°C are guaranteed by design based on final test characterization results.
Note 2: Corresponds to 256 DPWM cycles or 32768 MODE cycles.
Note 3: The MODE pin thresholds are only valid while the part is operating. When in shutdown, V
Note 4: The amplitude is measured with the following circuit:
