Low power dual operational amplifiers
Product specification
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.
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 (400µA)—essentially independent of
supply voltage (1mW/op amp at +5VDC)
• Low input biasing 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 V+ 1.5VDC swing
