The HA-2705 is a general purpose amplifier which operates at very low power levels without compromising large signal response characteristics or output drive capability. Advanced circuit design techniques and the use of vertical NPN and PNP transistors make possible the attainment of very high gain with a single stage of voltage amplification. This ensures closed loop stability even in the critical unity gain follower mode, without the use of external compensation components.
