Description
This pin can be used to power down the IC to converse power, or for muting, or
both. When at a logic “LOW”(less than 0.8V), the IC is enabled for normal
operation. When at a logic “HIGH”(2.0V ~Vcc), the IC is disabled. If Mute is open,
that is equivalent to a logic “LOW”.
A capacitor at this pin increase power supply rejection, and affects turn-on time.
This pin can be left open if the capacitor at pin 1 is sufficient.
Analog Ground for the amplifiers. A 1.0F capacitor at this pin (with a 5.0F
capacitor at pin 8) provides 52dB(typical) of power supply rejection. Turn-on time
of the circuit is affected by the capacitor on this pin. This pin can be used as an
alternative input.
Amplifier input. The input capacitor and resistor set low frequency roll-off and input
impedance. The feedback resistor is connected between this pin and output 1.
Amplifier a’s output. The DC level is about (Vcc-0.7V)/2.
DC supply voltage is applied to this pin(Vcc=2.0V ~16.0V)
Ground pin
Amplifier 2’s output. This signal is equal in amplitude, but 180° out of phase with
that t output 1 the DC level is about(Vcc-0.7V)/2.
