AU2902Low power quad operational amplifier

August 31, 1994 853-1634 13721

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: 3V

DC

to 30VDC or dual

supplies: ±1.5V

DC

to ±15V

DC

•Very low supply current drain: 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

•Differential input voltage range equal to the power supply voltage

•Large output voltage: 0V

NOTES:

1. Derate above 25°C at the following rates:
N package at 11.4mW/°C
D package at 8.3mW/°C

2. Short–circuits from the output to V

CC

+ can cause excessive heating and eventual destruction. The maximum output current is approximately

40mA, independent of the magnitude of V

CC

. At values of supply voltage in excess of +15VDC continuous short–circuits can exceed the

power dissipation ratings and cause eventual destruction.

3. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector–base junction of the

input PNP transistors becoming forward biased and thereby acting as input bias clamps. In addition, there is also lateral NPN parasitic tran­sistor action on the IC chip. This action can cause the output voltages of the op amps to go to the V+ rail (or to ground for a large overdrive)
during the time that the input is driven negative.
