AU2902 NXP Semiconductors, AU2902 Datasheet - Page 2

• Manufacturer Part Number: AU2902
• Description: Low Power Quad Operational Amplifier
• Manufacturer: NXP Semiconductors

to operate from a single power supply over a wide range of voltages.
Philips Semiconductors
DESCRIPTION
The AU2902 consists of four independent, high-gain, internally
frequency-compensated operational amplifiers designed specifically
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.
