Usage Note
1. Input coupling capacitor (C3 and C5)
Since the high pass filter is formated by the input coupling capacitor C3, C5 and the input resistance R1, R4, low
frequency attenuates. Therefore, it is necessary to select the capacitance value with due considelation of passband. The
capacitance value influences a shock noise when the switch is turned on, caution is demanded because the level of
shock noise becomes large when a bigger capacitance value is set.
2. The 3rd pin capacitor (C4)
The power supply ripple is reduced by the 3rd pin capacitor C4. The Ripple rejection ratio improves when the
capacitance value is large. However, this capacitor influences the shock noise and rise time of amplifier.
Please design with both characteristics in mind.
3. Standby pin (pin 2)
The standby mode and the operation mode can be switched by controlling the standby pin.
Standby mode ⇒ V2 = 0 to 0.3V
Operation mode ⇒ V2 = 1.9 to V
V
CC
In addition, caution is necesssary since the current I flows to the standby pin when the standby pin is used by
ST
working with power supply as shown in FIG.1.

Fig. 1
4. Power supply bypass capacitor (C2)
The bypass capacitor must be inserted, as close as possible to the power supply pin (pin 7).
5. Short-circuit between terminals
Turning on the power supply with the short-circuit between terminals leads to the deterioration and destruction of IC.
When fixing the IC to the substrate, please check that the solder is not short-circuited between the terminals before
turning on the power.
6. Load Short-circuit
Leaving the IC in the load short-circuit for many hours leads to the deterioration and destruction of the IC.
The load must not be short-circuited absolutely.
7. Maximum rating
When the rated value used is just below to the absolute maximum ratings value, there is a possibillity to exceed the
maxixmum rating value with slight extrusion variable. Also, it can be a destructive accident.
Please use within the absolute maximum ratings with sufficient variation margin of supply voltage.
