L7597 Resistive Subscriber Line Interface Circuit (SLIC), Ring
Electrical Characteristics
In general, minimum and maximum values are testing requirements. However, some parameters may not be tested
in production because they are guaranteed by design and device characterization. Typical values reflect the design
center or nominal value of the parameter; they are for information only and are not a requirement. Minimum and
maximum values apply across the entire temperature range (–40
°
C to +85
°
C) and entire battery range (–35 V
to –60 V). Unless otherwise specified, typical is defined as 25
°
C, V

1. Not to exceed 26 grams of water per kilogram of dry air.
2. This parameter is not tested in production. It is guaranteed by design and device characterization.

BATL
power supply rejection depends on the battery noise cancellation circuit. The performance stated here applies to V
BATL
only
during the talk state and V
BATH
only during the on-hook transmission state and assumes proper battery noise cancellation; i.e., a 0.1
μ
F
capacitor from V
BF
to CBN (see Figure 14). The 1 kHz—3 kHz power supply rejection can be improved by at least 6 dB with an additional
series RC (50 k
+ 47 pF) network connected from RGBN to AGND (see Figure 14).
