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
