8.3 Monitoring Typical Performance Plots
Unless otherwise noted, all VMON/IMON plots use the amplifier as the signal source and all measurements were taken
using an 8
 + 33 H load. All listed load inductances include any measured inductances contained in the connection to
the load. No EMI filtering is populated on the amplifier outputs (OUT±).
Figure 8-9. Frequency Response @ 1 W—
Fixed-Boost Mode (VBST = 5 V, Refer to Amplitude @ 1 kHz)
