Low power dual operational amplifier
AU2904
DESCRIPTION
PIN CONFIGURATION
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
Top View
• Large DC voltage gain: 100dB
• Wide bandwidth (unity gain): 1MHz (temperature-compensated)
• Wide power supply range Single supply: 3V to 30V or dual
UNIQUE FEATURES
DC
DC
supplies: ±1.5V to ±15V
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.

• Very low supply current drain (400µA): essentially independent of
supply voltage (1mW/op amp at +5V
)

The unity gain crossover frequency and the input bias current are
temperature-compensated.
• Low input bias current: 45nA (temperature-compensated)

• Low input offset voltage: 2mV and offset current: 5nA

• Differential input voltage range equal to the power supply voltage
• Large output voltage: 0V to V+-1.5V swing

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 , continuous short-circuits can exceed the power
DC
dissipation ratings and cause eventual destruction.
