Notes:
(1) The circuit can be supplied either at V
or without the use of the internal voltage regulator atV
. The circuit also operates at a supply
voltage V
lower than 10V. In this case the ripple rejection of V
S2
is valid, because the voltage regulator saturates to a saturation voltage
of about 0.8V.
(2) The selected input is grounded thru the 2.2
μ
F capacitor.
(3) Bass and Treble response see attacheddiagram. The center frequency and quality of the resonance behaviour canbe choosenby the
external circuitry. A standard firstorder bassresponse can berealized by a standard feedbacknetwork.
