compensated)
■ Low input offset current: 2 nA
■ Input common-mode voltage range includes
negative rail
■ Differential input voltage range equal to the
power supply voltage
■ Large output voltage swing 0 V to (V_CC+ -1.5 V)
Description
This circuit consists of two independent, high
gain, internally frequency-compensated
operational amplifiers designed specifically for
automotive and industrial control systems. It
operates from a single power supply over a wide
range of voltages. The low power supply drain is
independent of the magnitude of the power supply
voltage.
Application areas include transducer amplifiers,
DC gain blocks and all the conventional op-amp
circuits which can now be more easily
implemented in single power supply systems. For
example, these circuits can be directly supplied
from the standard +5 V which is used in logic
systems and easily provides the required
interface electronics without requiring any
additional power supply.
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 a single power supply.
