Direct Access Arrangement for T elephone Line Interface
Figure 42 illustrates a +5 V only transmit/receive telephone line
interface for 600
transmission systems. It allows full duplex
transmission of signals on a transformer coupled 600
line in a
differential manner. Amplifier A1 provides gain that can be ad-
justed 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/
AD8534s, the largest signal available on a single +5 V supply is
approximately 4.5 V p-p into a 600
transmission system.
Amplifier A3 is configured as a difference amplifier for two rea-
sons: (1) It prevents the transmit signal from interfering with
the receive signal and (2) it extracts the receive signal from the
transmission line for amplification by A4. A4’s gain can be ad-
justed in the same manner as A1’s 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 AD8531/AD8532/AD8534’s 8-pin SOIC or T SSOP
footprint and this circuit offers a compact, cost-sensitive solution.
