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: 3V_DC to 30V_DC 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_DC to V+-1.5V_DC 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.
