LA4600
Monolithic Linear IC
LA4600
Audio Power Amplifier for
Radio Cassette Recorders
Overview
The LA4600 is an audio power amplifier which
requires minimum count of external parts by
incorporating BS capacitor, NF capacitor; and
oscillation prevention CR components into the IC
circuitry.
Functions
• Output power : VCC = 12V/4Ω............
VCC = 9V/4Ω ..............
• Built-in stanby switch
• Built-in overheat protection (TSD)

4. P.P (pop noise) pin (6)
Voltage at pin 6 =.. VCC – VCE (approx. 0.3V) – 5.6V + 5.6V

• The recommended value for the P.P capacitor is 4.7 µF.
When capacitance is lower than 2.2 µF, pop noise when setting the standby
pin to Low (power OFF) will increase.
When capacitance is higher than 10 µF, the sound will not be cut off when
setting the standby pin to Low (power OFF).

5. Muting
The output signal can be controlled by
connecting pin 5 (Filter) to ground via a
resistance of 300 to 500 Ω. If resistance
is higher than 750 Ω, the suppression
ratio will decrease.
