The RS52X families of products offer low voltage
operation and rail-to-rail input and output, as well as
excellent speed/power consumption ratio, providing
an excellent bandwidth (3.6MHz) and slew rate of
1.8V/us. The op-amps are unity gain stable and
feature an ultra-low input bias current.
The devices are ideal for sensor interfaces, active
filters and portable applications. The RS521S,
RS522S include a shutdown mode. Under logic
control, the amplifiers can be switched from normal
operation to a standby current that is less than
1uA.The RS52X families of operational amplifiers are
specified at the full temperature range of −40°C to
+125°C under single or dual power supplies of 2.5V
to 5.5V.

ESD SENSITIVITY CAUTION
ESD damage can range from subtle performance
degradation to complete device failure. Precision
integrated circuits may be more susceptible to
damage because very small parametric changes
could cause the device not to meet its published
specifications.
(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
implied.
(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.
