Notes on Operation
1. Power supply
The CXA1597 is designed basically for positive/negative dual power supplies, and can also operate with a
single power supply. Connect the power supplies for each case as shown below:

(Pin 7)
GND (Pin 5) DGND (Pin 3)

For a single power supply, connect a decoupling capacitor (10μF or more) to the GND (VG) pin (Pin 5).
The ripple rejection ratio depends on the capacitance of this capacitor.
2. Operation mode control (NORM/CrO

/METAL tape, NORM/HIGH speed)
The CXA1597 incorporates an electronic switch and its operation is controlled by the DC voltage applied to
the two mode control pins - TAPE EQ pin (Pin 3) and SPEED pin (Pin 1).
The mode control voltages are as follows
The voltages in the table to the left are the
values relative to DGND.

If the switching click noise presents a problem, add time constant circuits of 0.1 to 1s to the mode control
pins. Since the mode control circuit has a linear region of approximately ±300mV, this time constant circuit
may effectively reduce the switching click noise.
