SIZE PACKAGES: SOT23-5
DESCRIPTION
The RS8031, RS8032, RS8034, 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
(15kHz) and slew rate of 7.5V/ms. 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 RS8031,
RS8032, RS8034 families of operational amplifiers
are specified at the full temperature range of −40°
C
to +125° under single or dual power supplies of
C
1.4V 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.
