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.
FEATURES
Internally frequency-compensated for unity gain
Large DC voltage gain: 100 dB
Wide bandwidth (unity gain): 1 MHz (temperature-compensated)
