Sanyo LA3210 Specifications

Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.

SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other
parameters) listed in products specifications of any and all SANYO products described or contained
herein.

Description of External Parts

C1 : Input coupling capacitor (10µF)

DC current blocking capacitor used to prevent the DC current applied to the base from mixing in the AC signal
source.
The C1 is calculated using C1=1/2πfTzi (zi : input resistance, fT : low cutoff frequency). If the capacitance value
is too decreased, your set is subjected to inductive hum. We recommend using a capacitor of 2.2µF or greater. We
also recommend using 6.3WV or greater because the chemical capacitor becomes less leaky as the withstand
voltage gets higher.

C2 : Decoupling capacitor (33µF)

Used to bypass the power source ripple.
Decreasing the capacitance value makes the starting time shorter. We recommend using a capacitor of 33µF.

C3 : Bypass capacitor (100µF)

Used to AC-Short the emitter resistance and prevent AC components from being fed back to the input.

C4 : Output capacitor (10µF)

Used to block DC components and pass AC Components only.
The C4 is calculated using C4=1/1πfL · RL (fL : low cutoff frequency, RL : load resistance).

C5 : Phase compensation capacitor (30pF)

Used to prevent high-frequency oscillation caused by phase shift when a deep feedback is provided. It should be
noted that the high frequency response depends on the capacitance value of C5.

Continued from preceding page.
R1 : Decoupling resistor used to bypass the power source ripple through C2.
R2 : Collector resistor of the first stage transistor of IC. Taken as load resistance in terms of AC.
C6, R3, R4 : Equalizer parts on which the closed-loop voltage gain depends. NAB 4.75cm/s is provided.

Proper Cares in Using IC

1. If the IC is used in the vicinity of the maximum rating, even a slight variation in conditions may cause the maxi­mum rating to be exceeded, thereby leading to a breakdown. Allow an ample margin of variation for supply
voltage, etc. and use the IC in the range where the maximum rating is not exceed.

2. Pin-to-pin short
If the supply voltage is applied when the space between pins is shorted, a breakdown or deterioration may occur.
When installing the IC on the board or applying the supply voltage, make sure that the space between pins is not
shorted with solder, etc.
