Main volume control block fader control common terminals. The impedance of pattern
connected to these pins should be as low as possible. Since L–V
SS
(R–V
SS
) and V
SS
have not been connected inside the LSI, they should be connected together on the outside
in conformance with their individual specifications. Particular attenuation should be paid to
the capacitance assigned to the capacitors put between L–V
SS
(R–V
SS
) and V
SS
, which
will emerge as a residual resistive component when control is turned down for maximum
attenuation.
Intra-IC latch resetting terminal
Control-setting data at the internal latch will be indeterminate when power has just been
switched on, so that by engaging the “L” level of this pin at power-on, the fader control
may be set at its –
∞
position and muting behaviour is engaged (Note: V
DD
to V
EE
Level).
Chip enable terminal. When this pin is made “H” to “L”, data is written in the internal latch,
activating the various analog switches. When the “H” level is then restored, transfer of the
data will be enabled.
Input terminals for serial data and clock that serve control purposes.
