AU2904Low power dual operational amplifier

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)
•Wide power supply range Single supply: 3V
DC
to 30VDC or dual
supplies: ±1.5V
DC
to ±15V
DC
•Very low supply current drain (400µA): essentially independent of
supply voltage (1mW/op amp at +5V
DC
)
•Low input bias current: 45nA
DC
(temperature-compensated)
•Low input offset voltage: 2mV
DC
and offset current: 5nA
DC
•Differential input voltage range equal to the power supply voltage
•Large output voltage: 0V

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.
