CDB4361
8. PERFORMANCE PLOTS
The plots in the following section were acheived using an Audio Precision System 2700 and a randomly chosen pro-
duction CDB4361. In some cases the performance may be limited by the CDB4361. All measurements were taken
at room temp using the standard AP filter options (20 Hz to 22 kHz) with default board settings and nominal
datasheet voltages applied unless otherwise noted.
