Figure 4 - VCLAMP biasing
In a bridged system, stated in terms of the components described in the feedback section, the values for Ra
and Rb are determined as follows (Rd = 0.176 x Ra):
Ra
=
Rb
×

0.952 × R3
R2 || 25K
−
0.048

where R2||25k is the parallel combination of R2 and 25k Ohms. In a single ended (half bridge) system, the
component value relationships would be, stated in terms of the components in the feedback section:
Ra
=
Rb × _{}
1.90 × R3
R1|| R2 || 25K
+
0.90 _{}
where Rd = 0.176 x Ra, and R1||R2||25k is the parallel combination of R1, R2, and 25k Ohms.
