WS722377
13MHz Low Noise CMOS Operational
Amplifiers
Descriptions
WS722377 is wide bandwidth CMOS amplifier that
provides very low noise, low input bias current, and low
offset voltage while operating on a low quiescent
current of 1.3mA per channel.
WS722377 is optimized for low voltage, single supply
applications. The exceptional combination of ac and dc
performance make them ideal for a wide range of
applications, including small signal conditioning, audio,
and active filters. In addition, these parts have a wide
supply range with excellent PSRR, making them
attractive for applications that run directly from
batteries without regulation.
The WS722377 is available with MSL 3 Level in
SOP-8L, MSOP-8L and DFN3x3-8L packages.
Standard products are Pb-Free and halogen-Free.

Note:
1. Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions
for extended periods may degrade device reliability. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those specified is not supported.
2. Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5V
beyond the supply rails should be current limited to 10mA or less.
3. Short-circuit to ground, one amplifier per package. Differential voltages are at +IN with respect to -IN.
