1. Termihal(D is Input stage GND, terminal(® ls output stage GND.
2. Closed-loop voltage gain of the amplifier is determined by the ratio ; (R1+R2)/R1T
TA7222AP isfixed at typically 53.0 dB for designing minimum external components.
. When higher closed loop gain is desired, the gain can be increased by connecting
a resistor between pin (5)and pin tti) . Open loop gain is obtained by shortening
pin (li) and pin © .
. When lower closed loop gain is desired, the following two ways can be used.
A. Series connecting a resistor and a capacitor between pin @and pin@.
B. Series adding a resistor to pin ca
Both A and is, lower closed loop gain than 40 dB is not recommended. And also, ripple
rejection ratio is decreased by using B configuration in such a case, connecting a
capacitor from pin CD to ground is recommended.
(Fig.2,3,4 show these ways.) _
3. For applications requiring high ripple rejection ratio, an excellent supply
voltage ripple rejection ls obtained by connecting a capacitor (recommended
value 4.7pF) between pin ©and ground.
(R.R-t shows these characteristics)
4. Terminalcg ls Audio Muting Control Input. _
. When control Input is low state (; open or below 0.3V), muting circuit does not
operate, OFF.
. When control input is high state (; above 1.0V), muting circuit, then, operates,
ON. (Refer to Fig.5)
