Output stage
Poor current capability and low cutoff frequency are well known limits of the standard lateral
PNP.
Composite PNP-NPN power output stages have been widely used, regardless their high
saturation drop. This drop can be overcome only at the expense of external components,
namely, the bootstrap capacitors. The availability of 4A isolated collector PNP (ICV PNP)
adds versatility to the design.
The performance of this component, in terms of gain, V
in
top bottom isolation techniques, allowing the implementation of low leakage diodes, too. It
guarantees BV
Basically, the connection shown in
voltage swing is rail-to-rail, limited only by the V
the range of 0.3Ω each. Then, the gain VOUT/VIN is greater than unity, approximately
1+R2/R1. (VCC/2 is fixed by an auxiliary amplifier common to both channel).
