MOTOROLA ANALOG IC DEVICE DATA
PIN FUNCTION DESCRIPTION
Symbol
Pin
Description
CD
1
Chip Disable – Digital input. A Logic “0” (<0.8 V) sets normal operation. A logic “1” (
≥
2.0 V) sets the power down
mode. Input impedance is nominally 90 k
.
FC2
2
A capacitor at this pin increases power supply rejection, and affects turn–on time. This pin can be left open if the
capacitor at FC1 is sufficient.
FC1
3
Analog ground for the amplifiers. A 1.0
μ
F capacitor at this pin (with a 5.0
μ
F capacitor at Pin 2) provides
(typically) 52 dB 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.
Vin
4
Amplifier input. The input capacitor and resistor set low frequency rolloff and input impedance. The feedback
resistor is connected to this pin and VO1.
VO1
VCC
GND
5
Amplifier Output #1. The dc level is
≈
(VCC – 0.7 V)/2.
DC supply voltage (+2.0 V to +16 V) is applied to this pin.
6
7
Ground pin for the entire circuit.
VO2
8
Amplifier Output #2. This signal is equal in amplitude, but 180
°
out–of–phase with that at VO1.
The dc level is
≈
(VCC – 0.7 V)/2.
