Norton_ac_amplifier_with_±15__V_supplies

This circuit uses one section of an LM3900 to form an ac-coupled amplifier, where both inputs bias at one VBE above the -VEE voltage (about -15 V). With RF=RB, VO will bias at about 0 V to allow a maximum output swing.Because pin 7 is common to all four amplifiers in the package, the other amplifiers are also biased for operation with ±15-V supplies.
