Operating Modes
Fixed-Frequency (FFM) Mode
The MAX9701 features two fixed-frequency modes.
Connect SYNC to GND to select a 1.1MHz switching fre-
quency. Leave SYNC unconnected to select a 1.4MHz
switching frequency. The frequency spectrum of the
MAX9701 consists of the fundamental switching frequen-
cy and its associated harmonics (see the Wideband FFT
graph in the
Typical Operating Characteristics
). Program
the switching frequency so the harmonics do not fall
within a sensitive frequency band (Table 1). Audio repro-
duction is not affected by changing the switching fre-
quency.
