1) Pin 6
This pin makes first LPF together with internal registors.
When a value of C2 is 0.033 µF, cutoff frequency is 500 Hz.
2) Pin 45, pin 46
This gain is
VR4 + R9
GV =
R9
It is necessary that VR4 = 3.9 kΩ, R9 = 1 kΩ for amplifier gain of five times.
The HPF is composed with R9 and C20, then if R9 is 1 kΩ, suitable value of C20 is 3.3 µF.
3) Pin 47
This pin makes second LPF together with internal registors.
When a value of C21 is 0.033 µF, cutoff frequency is 500 Hz.
4) Pin 48, pin 49
This purpose is DC cut. Suitable value of C22 is 10 µF (bipolar), because input impeadance of speaker power
amplifier is 2 kΩ.
• Pin 7, pin 8 (L-ch., R-ch. speaker input)
If no resistors are connected to pin 7 and pin 8 from previous stage, the BTL output has the gain of 40 times.
If input of 1.4/40 V[rms] or more is possibly inputted, the input should be attenuated by connecting resistors to pin
7 and pin 8 from previous stage because the output dynamic range is about 1.4 V[rms].
The gain at BTL output is 2 kΩ/(R1+2 kΩ) × 40, where R1 and R2 are the resistance of resistors of connected
to pin 7 and pin 8 from the previous stage and R1 = R2.
Supposing that max output level of headphone is 1 V[rms], suitable value of R1 and R2 is 25 kΩ, because gain
of speaker power amplifier is 32 dB.
• Pin 9 (ripple filter of speaker amplifier)
Recommended value is 1 µF.
If capacitor value is bigger, rise time at standby is longer.
If capacitor value is smaller, rise time at stanby is shorter, but there are possibilities of pop sound occurrence
and deterioration of power supply ripple rejection, cross talk and THD.

1. 1) Make sure that the IC is free of otput-VCC short, output-GND short and load short.
2) The thermal protection circuit operates at a Tj of approximately 150°C. The thermal protection circuit is reset
automatically when the temperature drops.
3) Beep in pin should not be down lower than − 0.3 V.
4) The IC should not be inserted in reverse.
2. The IC has the possibility of break-down as follows.
1) Reverse connection of the VCC and GND pins.
2) The power supply connection to output-pins (pin 55, pin 54, pin 2 and pin 3), when VCC and GND are opened.
3) Output-GND short, when GND pin is opened.
4) Output pins (pin 55, pin 54, pin 2 and pin 3) short to GND.
5) Output pins (pin 55, pin 54, pin 2 and pin 3) short to VCC
6) Short between outputs.

ing, or use of the products, therefore, ask for the most up-to-date Product Standards in advance to
make sure that the latest specifications satisfy your requirements.
(5) When designing your equipment, comply with the guaranteed values, in particular those of maxi-
mum rating, the range of operating power supply voltage and heat radiation characteristics. Other-
wise, we will not be liable for any defect which may arise later in your equipment.
Even when the products are used within the guaranteed values, redundant design is recommended,
so that such equipment may not violate relevant laws or regulations because of the function of our
products.
(6) When using products for which dry packing is required, observe the conditions (including shelf life
and after-unpacking standby time) agreed upon when specification sheets are individually exchanged.
(7) No part of this material may be reprinted or reproduced by any means without written permission
from our company.
