ANALOG CHARACTERISTICS - COMMERCIAL GRADE (-CZZ)
Test conditions (unless otherwise specified): T
A
= 25C; Input test signal is a 997 Hz sine wave through recom-
mended inputs as seen in Figure 6 on page 14; source impedance less than or equal to 2.5 k; valid with FILT+
and VQ components as shown in Figure 3 on page 11; measurement bandwidth is 10 Hz to 20 kHz; Fs = 48 kHz
or 96 kHz.
Notes:
