DESCRIPTION
The RS6331, RS6332, RS6334, RS6331S,
RS6332S 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 (1.1MHz) and slew rate of
0.5V/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 RS6331S,
RS6332S 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 RS6331, RS6332, RS6334, RS6331S,
RS6332S families of operational amplifiers are
specified at the full temperature range of −40° to
C
+125° under single or dual power supplies of 2.5V
C
to 5.5V.

(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.
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.
