Notes on Operation
• Connect the power supply side of the by-pass capacitor between the power supply and GND as close to the
pin as possible.
• Take care not to allow interference signals to enter Pin 32 (BIAS). If interference signals enter Pin 32, the
signal S/N, cross talk and MUTE will deteriorate. Therefore, connect the by-pass capacitor, etc. as close to
the pins as possible.
• For dual surface boards, using one side as a solid earth is best.
• Pins 2, 8, 10, 12, 14, 16, 18, 24 and 28 are NC (not connected) pins. Connect these NC pins to GND. If these
NC pins are not connected to GND, the cross talk and other desired values indicated in the Electrical
Characteristics cannot be obtained.
• Input pins of Pins 1, 3, 5, 7, 23, 25, 27, 29 and 31 are biased to approximately 4.2 to 4.7V. Therefore, care
should be taken for the capacitance polarity.
• Output pins of Pins 9, 11, 13, 15 and 17 are biased to approximately 3.8 to 4.8V. Therefore, care should be
taken for the capacitance polarity.
