Caution and Application Method
(Description is made only on the single channel.)
Voltage Gain Adjustment
This IC has no NF (negative feedback) Pins. Therefore, the voltage gain can not be adjusted, but it makes
the device a space and total costs saver.
Input C
Figure 1 Block Diagram
The voltage gain of amp.1 I GV1 = OdB
The voltage gain of amp.2A, B 1 sz = 20dB
The voltage gain of BTL connection: GV (BTL) = 6dB
Therefore, the total voltage gain is decided by expression below.
Gv= Gv1+Gv2+GV(BTL)= 0+20+6=26dB
Standby SW Function (pin 4)
By means of controlling pin 4 (standby pin) to
High and Low, the power supply can be set to ON
and OFF. The threshold voltage of pin 4 is set at Vcc
about 3VBE (typ.), and the power supply current is ON lPower
about 2 " (typ.) in the standby state. = = 2 VBE

Advantage of Standby SW
(1) Since VCC can directly be controlled to ON or OF F by the microcomputer, the switching relay can be
omitted.
(2) Since the control current is microscopic, the switching relay of small current capacity is satisfactory
for switching.

3. Muting Function (pin 22)
Audio muting function is enabled when pin 22 is Low. When the time constant of the muting function is
determined by R1 and C4, it should take into account the pop noise. The pop noise which is generated when
the power or muting function is turned ON/OFF will vary according to the time constant. (Refer to Figure 4
and Figure 5.)
The pin 22 is designed to operate off 5 V.
Moreover, this terminal (pin 22) serves as the source switch of current of an internal mute circuit. And it is
designed so that the discharge current of this terminal (pin 22) may serve as 200 pA. The outside pulrup
resistor R1 is determind on the basic of this value.
ex) When control voltage is changed in to 6 V from 5 V.
6V/5Vx47k=56k
To obtain enough mute attenuation, a series resistor, R1 at pin 22 should be 47 kn or more.

5. Pop Noise Suppression
TB2903HQ
Since the AC-GND pin (pin 16) is used as the NF pin for all amps, the ratio between the input
capacitance (C I) and the AC-to-GND capacitance (C6) should be 1:4.
Also, if the power is turned OFF before the C1 and C6 batteries have been completely charged, pop noise
will be generated because of the DC input unbalance.
To counteract the noise, it is recommended that a longer charging time be used for C2 as well as for C1
and C6. Note that the time which audio output takes to start will be longer, since the C2 makes the muting
time (the time from when the power is turned ON to when audio output starts) is fix.
The pop noise which is generated when the muting function is turned ON/OFF will vary according to the
time constant of C4.
The greater the capacitance, the lower the pop noise. Note that the time from when the mute control
signal is applied to C4 to when the muting function is turned ON/OFF will be longer.

The absolute maximum ratings of a semiconductor device are a set of specified parameter values, which must not
be exceeded during operation, even for an instant. If any of these rating would be exceeded during operation, the
device electrical characteristics may be irreparably altered and the reliability and lifetime of the device can no
longer be guaranteed. Moreover, these operations with exceeded ratings may cause break down, damage and/or
degradation to any other equipment. Applications using the device should be designed such that each maximum
rating will never be exceeded in any operating conditions. Before using, creating and/or producing designs, refer to
and comply with the precautions and conditions set forth in this documents.
