Conclusions

The amplifiers described can be built into small modules,

thus reducing the overall size of the recorders. The low

voltage economy version built with miniature components

and powered from a watch battery may result in a microminiature

module suited for special applications. The total current

drain can be as low as 1mA for extended battery life.
