The conception of multiple output current operational amplifier and its applications in current amplifiers circuits having amplification digitally tuned, has been presented. The general structure of the realisation of a sinusoidal generator with one MOCOA and digitally tuned parameter such as a condition and frequency of oscillation, has been described. One versions of a sinusoidal oscillator with RC elements, have been shown. Simulations the form of generated oscillations as amplifier output current, have been carried out and the effect of tuning of its amplification on the form of those characteristics, has been investigated. The system may be applied in high stable acoustical generators.
