Descriptions
SOP-8L
WS742905 consist of dual channel independent, high
MSOP-8L
gain, internally frequency compensated operational
amplifiers which are designed specifically to operate
from a single power supply over a wide range of
voltages. These devices are particularly useful in
interface circuits with digital systems and can be
operated from the single common 5VDC power supply.
SOP-8L/MSOP-8L
The WS742905 is available in 8-pin SOP and MSOP
packages.
Standard
products
are
Pb-Free
Pin configuration (Top view)
and
halogen-Free.

Note:
1.
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the
device. These are only stress ratings, and functional operation of the device at these or any other
conditions beyond those indicated under recommended operating conditions are not implied. Exposure
to absolute-maximum-rated conditions for extended periods may affect device reliability.
2.
All voltage values, except differential voltage are with respect to network terminal.
3.
Differential voltages are at IN+ with respect to IN–.

Note:
1.
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the
device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device
reliability and lifetime.
2.
A heat sink may be required to keep the junction temperature below the absolute maximum rating when
the output is shorted indefinitely.
3.
Thermal resistance varies with the amount of PC board metal connected to the package. The specified
values are for short traces connected to the leads.
4.
Full power bandwidth is calculated from the slew rate FPBW = SR/(π • VP-P).
