PIN DESCRIPTION

Symbol
Description
1
Input (+)
Analog Ground for the amplifiers. A 1.0
μ
F capacitor at this pin (with a 5.0
μ
F capacitor at
pin 8) provides 52dB (Typ) 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.
2
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 output1.
3
Output 1
The output of Amplifier 1. DC Level is (V
CC
— 0.7V)/2.
4
V
CC
GND
DC supply voltage (+2.0 — + 16V) is applied to this pin.
5
Ground pin.
6
Output 2
The output of Amplifier 2. This signal is equal in amplitude, but 180
°
out of phase with that
at output1. The DC level is (V
CC
— 0.7V)/2.
7
Mute
This pin can be used to power down the IC to conserve power or for muting, or both.
When at a logic Low (0 to 0.8 volts), the S1T8602B is enabled for normal operation. When
at a logic High (2.0 to V
CC
volts), the IC is disabled. If Mute is open, that is equivalent to a
logic Low.
8
Ripple Rejection
A capacitor at this pin increases power supply rejection, and affects turn-on time. This pin
can be left open if the capacitor at pin 1 is sufficient.
