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

The circuit is intended for use in applications that require fast
large signal response with low power dissipation and for
instrumentation applications in which low offset voltage, low
bias current drift, large voltage gain and high common mode
rejection are necessary. Full output short circuit protection
and the large differential input breakdown enable the device
to withstand a variety of fault conditions.
