ANALOG CHARACTERISTICS - AUTOMOTIVE GRADE (-DZZ)
Test conditions (unless otherwise specified): T
A
= -40C to 85C; Input test signal is a 997 Hz sine wave through
recommended 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.
