Figure 46 illustrates a 5 V only transmit/receive telephone line
interface for 600 Ω transmission systems. It allows full duplex
transmission of signals on a transformer-coupled 600 Ω line in
a differential manner. A1 provides gain that can be adjusted to
meet the modem output drive requirements. Both A1 and A2
are configured to apply the largest possible signal on a single
supply to the transformer. Because of the high output current
drive and low dropout voltage of the AD8531/AD8532/AD8534,
the largest signal available on a single 5 V supply is approximately
4.5 V p-p into a 600 Ω transmission system. A3 is configured as
a difference amplifier for two reasons: it prevents the transmit
signal from interfering with the receive signal, and it extracts
the receive signal from the transmission line for amplification
by A4. The gain of A4 can be adjusted in the same manner as
that of A1 to meet the input signal requirements of the modem.
Standard resistor values permit the use of single in-line package
(SIP) format resistor arrays.
