Fig.1

Block diagram and basic external components; Ic1 (at pin 9) and Ic2 (at pin 10) are control input currents;

Vc1 (at pin 9) and Vc2 (at pin 10) are control input voltages with respect to Vref = VP/2 at pin 8;

Z1 = Z2 = Z3 = Z4 = 22 kΩ; the input generator resistance RG = 60 Ω; the output load resistance

RL = 4,7 kΩ; the coupling capacitors at the inputs and outputs are Ci = 2,2 µF and Co = 10 µF

respectively.
