AU2902
Low power quad operational amplifier

853-1634 26837
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: 100 dB
Wide bandwidth (unity gain): 1 MHz (temperature-compensated)
Wide power supply range Single supply: 3 V
DC to 30 VDC or dual
supplies:
±1.5 VDC to ±15 VDC
Very low supply current drain: essentially independent of supply
voltage (1 mW/op amp at +5 VDC)
Low input bias current: 45 nA
DC (temperature-compensated)
Low input offset voltage: 2 mV
DC and offset current: 5nADC
Differential input voltage range equal to the power supply voltage
Large output voltage: 0 V
DC to VCC – 1.5 VDC swing
