Low power dual operational amplifiers
NE/SA/SE532/ LM158/258/358/A/2904
DESCRIPTION
The 532/358/LM2904 consists of two independent, high gain, internally frequency-compensated operational amplifiers internally frequency-compensated operational amplifiers designed specifically to operate from a single power supply over a wide range of voltages.
Operation from dual power supplies is also possible, and the low power supply current drain is independent of the magnitude of the power supply voltage.

UNIQUE FEATURES
In the linear mode the input common-mode voltage range includes ground and the output voltage can also swing to includes ground and the output voltage can also swing to ground, even though operated from only a single power supply voltage.
The unity gain cross frequency is temperature-compensated.
The input bias current is also temperature-compensated.
