Pin Description

This pin is for total circuit power supply.

This pin is for total circuit ground (GND).

This pin is for internal reference voltage (–2V).

This voltage is reference voltage for Drum FG and Drum

PG amplifiers.

These pins are for positive (+) inputs for the reel FG

amplifiers.

These pins are for negative (–) inputs for the reel FG

amplifiers.

These pins are for reel FG amplifier negative (–) inputs

equipped with 2k input resistors.

These pins are for reel FG amplifier negative (–) inputs

equipped with 80kΩ feed-back resistors.

These pins are for reel FG amplifier output pins.
