Single Supply Differential Line Driver
Signal distribution and routing is often required in audio systems,
particularly portable digital audio equipment for professional
applications. Figure 35 shows a single-supply line driver circuit
that has differential output. The bottom amplifier provides a
2 V dc bias for the differential amplifier to maximize the output
swing range. The amplifier can output a maximum of 0.8 V rms
signal with a 5 V supply. It is capable of driving into 600 Ω line
termination at a reduced output amplitude.

Single-Supply Differential Line Receiver
Receiving a differential signal with minimum distortion is
achieved using the circuit in Figure 36. Unlike a difference
amplifier (a subtractor), the circuit has a true balanced input
impedance regardless of input drive levels; that is, each input
always presents a 20 kΩ impedance to the source. For best
common-mode rejection performance, all resistors around the
differential amplifier must be very well matched. Best results
can be achieved using a 10 kΩ precision resistor network.

Figure 36. Single-Supply Balanced Differential Line Receiver
Pseudoreference Voltage Generator
For single-supply circuits, a reference voltage source is often
required for biasing purposes or signal offsetting purposes. The
circuit in Figure 37 provides a supply splitter function with low
output impedance. The 1 μF output capacitor serves as a charge
reservoir to handle a sudden surge in demand by the load as
well as providing a low ac impedance to it. The 0.1 μF feedback
capacitor compensates the amplifier in the presence of a heavy
capacitive load, maintaining stability.
The output can source or sink up to 12 mA of current with a
5 V supply, limited only by the 100 Ω output resistor. Reducing
the resistance increases the output current capability. Alternatively,
increasing the supply voltage to 12 V also improves the output
drive to more than 25 mA.
