Low power dual operational amplifier
Product specification
AU2904
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: 3VDC to 30VDC or dual
supplies: ±1.5VDC to ±15VDC
Very low supply current drain (400µA): 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 V+-1.5VDC swing

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.
