S1D15714 Series
6.6.1 Amplification circuit
By use of the amplification circuit being built into the S1D15714 Series, it is possible to make amplification of the
electric potential between V
double amplification.
amplification, quadruple amplification, triple amplification, double amplification and equal amplification.
1 When using the quintuple-boosting, connect the capacitor C1 between CAP1+ <–> CAP1–, between CAP2+ <–>
CAP2–, between CAP3+ <–> CAP1–, between CAP4+ <–> CAP2–, between V
CAP5+, CAP4+ and V
2 When using the quadruple-boosting, connect the capacitor C1 between CAP1+ <–> CAP1–, between CAP2+ <–>
CAP2–, between CAP3+ <–> CAP1– and between V
