Amplifier on (pin 5 voltage)
* If voltage is to be
applied to the Standby
pin (pin 5), a resistor
(Rx) should be
inserted to limit the
inflow current, as
required. Please refer
to the information
below.
The amplifier can be turned on and off by controlling
the level (high/low) of pin 5.
Applying a signal equal or greater than 1.5 V and
800
μ
A to pin 5 turns on the amplifier. (If 5 V is applied
directly to pin 5 the inflow current of pin 5 is approxi-
mately 4.5 mA.)
If a voltage, Vx, exceeding 5 V is to be applied, current
limiting resistor (Rx) should be inserted to limit the
inflow current to 4.5 mA. (See following equation.)
Rx = (Vx – 5 V) / 4.5 mA
If pin 5 is to be controlled by the microprocessor, the
pin 5 inflow current (Ix) should be optimized for the
capacity of the microprocessor by calculating Rx using
the following equation, as a general guideline, and then
confirming the inflow current through actual measure-
ment.
Rx = (Vx / Ix) – R1 (2 k
)
Note: The LA4635B is basically pin-compatible with the
LA4636, but there are partial differences in
operation and usage, including with regard to
externally connected parts.
