VITR
O
Transmit ac Output Voltage.
Output of internal AAC
amplifier. This output is a voltage that is directly propor-
tional to the differential ac tip/ring current.
Receive ac Signal Input (Noninverting).
This high-
impedance input controls to ac differential voltage on tip
and ring. This node is a floating input.
Receive ac Signal Input (Inverting).
This high-imped-
ance input controls to ac differential voltage on tip and
ring. This node is a floating input.
dc Output Voltage.
This output is a voltage that is
directly proportional to the absolute value of the differen-
tial tip/ring current. This is used to set the dc current limit
and the ring trip threshold.
Current-Limit Program Input.
A resistor is connected
from this pin to DCOUT to program the dc current limit for
the device.
Filter Capacitor.
Connect a capacitor from this node to
ground.
Filter Capacitor.
Connect a capacitor from this node to
CF2.
Ring Trip Filter.
Connect this lead to DCOUT via a resis-
tor and to AGND with a capacitor or a resistor capacitor
combination, depending on the ringing type, to filter the
ring trip circuit to prevent spurious responses.
SLIC Internal Reference Current.
Connect a resistor
between this pin and AGND to generate an internal refer-
ence current.
Analog Signal Ground.
Analog Power Supply.
User choice of 5 V or 3.3 V nom-
inal power supply.
Battery Supply 1.
High-voltage battery.
Battery Supply 2.
Low-voltage battery or power control
resistor.
Battery Ground.
Ground return for the battery supplies.
