Chip Disable-Digital input. A logic ”0” (<0.8V) sets normal operation. A logic ”I”（≥2.0V）sets
the power down mode. Input impedance is nominally 90KΩ
A capacitor at this pin increases power supply rejection, and affects turn-on time. This pin
can be left open it the capacitor at FC1 is sufficient.
Analog ground for the amplifiers. A 1uF capacitor at this pin (with a 5uF capacitor at pin 2)
provides 52dB(typically) 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 alternate input.
Amplifier input. The input capacitor and resistor set low frequency roll off and input
impedance. The feedback resistor is connected to this pin and VO1.
Amplifier Output #1. The dc level is ≈ (V
DC supply voltage (+2.0V ~ +16V) is applied to this pin.
Ground pin for the entire circuit.
Amplifier Output #2. This signal is equal in amplitude, but 180° out-of-phase with that at
VO1. The dc level is ≈ (V
