HA-2705

Low Power, High Performance

Operational Amplifier

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.

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.
