11 / 16 page REV. A OP471 –11– High-Speed Differential Line Driver The circuit of Figure 15 is a unique line driver widely used in professional audio applications. With ±18 V supplies, the line driver can deliver a differential signal of 30 V p-p into a 1.5 k W load. The output of the differential line driver looks exactly like a transformer. Either output can be shorted to ground without changing the circuit gain of 5, so the amplifier can easily be set for inverting, noninverting, or differential operation. The line driver can drive unbalanced loads, like a true transformer.

Low-Noise Amplifier High-Output Amplifier The amplifier shown in Figure 16 is capable of driving 20 V p-p into a floating 400 W load. Design of the amplifier is based on a bridge configuration. A1 amplifies the input signal and drives the load with the help of A2. Amplifier A3 is a unity-gain inverter which drives the load with help from A4. Gain of the high output amplifier with the component values shown is 10, but can easily be changed by varying R1 or R2. 10 0% 100 90 Figure 14.
