The voltage on IO3 or IO4 is measured with a reference to VCM. Hence, an input voltage
of V

the positive full scale value respectively. For that reason the voltage divider must be
referenced to VCM. The unknown foreign voltage V

The resistor directly connected to either Ring or Tip (R1, R3) should be high enough so
that the loop impedance will not be affected by them. Several M s, such as 10 M
would be a reasonable value. The following example illustrates the potential voltage
range that can be measured by choosing the values as:
•
•
The values given for the maximum and minimum voltage levels are:
•
•
•
The voltage range would span from 215 V to –212 V.
To measure small input voltages on IO3/IO4 more accurately, the integration function
may be enabled by setting bit LM-EN in register LMCR1 to 1 (see
To measure the ring voltage supplied to either Ring or Tip or even both (balanced
ringing) pins via IO3 and IO4, the rectifier can be enabled by setting bit LM-RECT in
register LMCR2 to 1.
