(1) Driver The driver uses a buffer to output one of the outputs from its preamplifier with no modification, and uses an inversion amplifier to invert the other output before sending it to the driver buffer. The inversion amplifier’s reference is the bias voltage generated internally (pin 7 voltage), and so the preamplifier output must make the zero level equal to the internal bias voltage.
