DIRECT ACCESS ARRANGEMENT
Figure 50 shows a schematic for a 5 V single-supply transmit/
receive telephone line interface for 600 Ω transmission systems.
It allows full-duplex transmission of signals on a transformer-
coupled 600 Ω line. Amplifier 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 differential
signal to the transformer. The largest signal available on a single
5 V supply is approximately 4.0 V p-p into a 600 Ω transmission
system. Amplifier A3 is configured as a difference amplifier to
extract the receive information from the transmission line for
amplification by A4. A3 also prevents the transmit signal from
interfering with the receive signal. The gain of A4 can be adjusted
in the same manner as A1 to meet the modem’s input signal
requirements. Standard resistor values permit the use of SIP
(single in-line package) format resistor arrays. Couple this with
the OP462 14-lead SOIC or TSSOP package and this circuit
offers a compact solution.
