FEATURES
DESCRIPTION
•
HIGH GAIN BANDWIDTH:1.1MHz
•
RAIL-TO-RAIL INPUT AND OUTPUT
±0.5mV Max Vos (RS6331P, RS6332P)
±0.8mV Max Vos (RS6334P)
•
INPUT VOLTAGE RANGE: -0.1V to +5.6V
with Vs = 5.5V
•
SUPPLY RANGE: +2.1V to +5.5V
•
SPECIFIED UP TO +125°C
•
Micro SIZE
The RS6331P, RS6332P, RS6334P 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 RS6331P, RS6332P and RS6334P has lower
offset, which is guaranteed not upper than ±0.5mV
(RS6331P, RS6332P) / ±0.8mV (RS6334P) at 25°C
with Vs = 5V, VCM = Vs/2.
The devices are ideal for sensor interfaces, active
filters and portable applications. The RS6331P,
RS6332P, RS6334P families of operational
amplifiers are specified at the full temperature range
of −40°C to +125°C under single supplies of 2.1V to
5.5V or dual power supplies of ±1.05V to ±2.75V.

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.

RS6331P, RS6332P, RS6334P
APPLICATION NOTES
The RS6331P, RS6332P, RS6334P, are high
precision, rail-to-rail operational amplifiers that can
be run from a single-supply voltage 2.1V to 5.5V
(±1.05V to ±2.75V). Supply voltages higher than 7V
(absolute maximum) can permanently damage the
amplifier.
INSTRUMENTATION AMPLIFIER
In the three-op amp, instrumentation amplifier
configuration shown in Figure2,
Rail-to-rail input and output swing significantly
increases dynamic range, especially in low-supply
applications.
V1
RS6334P
Good layout practice mandates use of a 0.1uF
capacitor place closely across the supply pins.
RS6334P
LAYOUT GUIDELINS
V2
Attention to good layout practices is always
recommended. Keep traces short. When possible,
use a PCB ground plane with surface-mount
components placed as close to the device pins as
possible. Place a 0.1uF capacitor closely across the
supply pins.
These guidelines should be applied throughout the
analog circuit to improve performance and provide
benefits such as reducing the EMI susceptibility.
