1.
Voltage gain
The closed loop voltage gain is determined by R1, R2.
= 34 (dB)
When R3 = 220
GV 30 (dB)
is given.
Toshiba has confirmed that the GV (min) is approximately 28 (dB) on a regular printed circuit board. However,
if the value of R2 + R3 is larger, the feedback voltage increases and oscillation will start. Determine the value of
R2 + R3 to ensure proper startup behavior under actual usage conditions.
