• VG settings are obtained using R4 and R5 according to the following equation:

log20·

R5

R4

40 dB is recommended.

• Low-frequency cutoff frequency settings are obtained using R4 and C3 according to the following

equation:

1

fL = 2π·R4·C3 [Hz]

When changing the VG setting, you should change R4 which requires a recheck of the low cutoff frequency

setting. When the VG setting is changed using R5, the setting should ensure R2 equals R5 so that VN

balance stability is maintained. If the resistor value is increased more than the existing value, VN balance

may be disturbed and result in deterioration of VN temperature characteristics.

: Differential constant-current bias resistor

: For oscillation suppression and phase compensation applications

(For use with differential stage applications)

: For oscillation suppression and phase compensation applications

(A Mylar capacitor is recommended for C4 for use with output stage applications)

: For oscillation suppression and phase compensation applications

Power stage (Must be connected near the pin) C6: Positive (+) power C9: Negative (–) power

: For oscillation suppression and phase compensation applications

(Oscillation suppression before power step clip)

: For oscillation suppression and distortion improvement applications

: Ripple filter circuit on positive (+) side.
