Low power quad operational amplifier
Product specification
AU2902
DESCRIPTION
The AU2902 consists of four independent, high-gain, internally
frequency-compensated operational amplifiers designed specifically
to operate from a single power supply over a wide range of voltages.
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.
FEATURES
• Internally frequency-compensated for unity gain
• Large DC voltage gain: 100dB
• Wide bandwidth (unity gain): 1MHz (temperature-compensated)
• Wide power supply range Single supply: 3VDC to 30VDC or dual
supplies: ±1.5VDC to ±15VDC
• Very low supply current drain: essentially independent of supply
voltage (1mW/op amp at +5VDC)
• Low input bias current: 45nADC (temperature-compensated)
• Low input offset voltage: 2mVDC and offset current: 5nADC
• Differential input voltage range equal to the power supply voltage
• Large output voltage: 0VDC to VCC-1.5VDC swing

NOTES:
1. VO ≈ 1.4VDC, RS=0Ω with VCC from 5V to 30V and over full input common–mode range (0VDC+ to VCC –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 VCC –1.5, but either or both inputs can go to +32V without damage.
4. Short–circuits from the output to VCC can cause excessive heating and eventual destruction. The maximum output current is approximately
40mA independent of the magnitude of VCC. At values of supply voltage in excess of +15VDC, continuous short–circuits can exceed the
power dissipation ratings and cause eventual destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers.
5. 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.
