(3) When an electrolytic capacitor is connected to input pins 1, 2 (or 23, 24), make the value of RIN1asequaltothatofRIN2as
possible.
The difference in the value between RIN1 and RIN2 causes the variation in amp output DC voltage at the time of F/R
switching. Therefore, the input DC voltage (voltage across RIN) must be made as equal as possible.
(4) The amplifier output characteristics are designed to be the same in the Nor Tape/High Speed (pin 15 GND/pin 6 VCC)and
Me Tape/Nor Speed (pin 15 VCC/pin 6 GND) modes. (Refer to sample application circuit, external constants.)
(5) When externally turning ON/OFF power supply pin 11 (by bringing pin 11 to +VCC/GND level) with a capacitor connected
to pin 13, connect external diode D, as shown below, so that no breakdown (or deterioration) of the IC system is caused by
ICD when the switch is turned OFF. When no capacitor is connected to pin 13, diode D is not required.
(6) The output MIX circuit is of the emitter follower configuration as shown below.
The MIX OUT output level VO MIX at the time a signal is applied to preamp1 (or preamp2) only is 1/2 as compared with
output levels VO1, VO2 at the time the same input signal is applied to both channels.
VO MIX = 1/2
VO1(= 1/2 × VO2)
where VO1= VO2
