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
; source impedance less than or equal to 2.5 k
; valid with FILT+
and VQ components as shown in
; measurement bandwidth is 10 Hz to 20 kHz; Fs = 48 kHz
or 96 kHz.
