AU2904
Low power dual operational amplifier
154
August 31, 1994
853-1633 13721
DESCRIPTION
The AU2904 consists of two independent, high-gain, internally
frequency-compensated operational amplifiers designed specifically
to operate from a single power supply over a wide range of voltages.
Operation from dual power supplies is also possible, and the low
power supply current drain is independent of the magnitude of the
power supply voltage.
FEATURES
Internally frequency-compensated for unity gain
Large DC voltage gain: 100dB
Wide bandwidth (unity gain): 1MHz (temperature-compensated)

)

UNIQUE FEATURES
In the linear mode the input common-mode voltage range includes
ground and the output voltage can also swing to ground, even
though operated from only a single power supply voltage.
The unity gain crossover frequency and the input bias current are
temperature-compensated.

from 5V to 30V and over full input common-mode range (0V
DC
+ to V

-1.5V).
2. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of
the output so no loading change exists on the input lines.
3. The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the
common-mode voltage range is V+-1.5, but either or both inputs can go to +32V without damage.
4. Due to proximity of external components, insure that coupling is not originating via stray capacitance between these external parts. This
typically can be detected as this type of coupling increases at higher frequencies.
5. Short-circuits from the output to V+ can cause excessive heating and eventual destruction. The maximum output current is approximately
40mA independent of the magnitude of V+. At values of supply voltage in excess of +15V
DC
, continuous short-circuits can exceed the power
dissipation ratings and cause eventual destruction.
