Low power quad operational amplifier |
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

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 VCC+ can cause excessive heating and eventual destruction. The maximum output current is approximately 40mA, independent of the magnitude of VCC. 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.
