2. Closed-loop Gain (f=1kHz)
• Closed loop voltage gain
GV=20log(Z1/Z3) (dB)
• Playback amplifier gain
GV=20log(R1/R3) (dB)
in low frequency
GV=20log(Z1/Z3) (dB)
in high frequency
• Recording amplifier gian
GV=20log(R1/R3) (dB)

3. Oscillation
When the closed-loop gain of amplifier is lowered, oscillation with occur. So the circuit
should be compensated by connecting of 10pF between pin 3 and pin 2, and 0.03 ㎌ in
series with 10Ω to the load end.
