OK06
6.5MHz, Rail-to-Rail I/O
CMOS Operational Amplifier
FEATURES
HIGH GAIN BANDWIDTH:6.5MHz
RAIL-TO-RAIL INPUT AND OUTPUT
0.8mV Typical Vos
INPUT VOLTAGE RANGE: -0.1V to +5.6V
with Vs = 5.5V
SUPPLY RANGE: +2.5V to +5.5V
SPECIFIED UP TO +125°
C
The devices are ideal for sensor interfaces, active
filters and portable applications. The OK06
operational amplifier are specified at the full
temperature range of −40° to +125° under single
C
C
or dual power supplies of 2.5V to 5.5V.
DESCRIPTION
The OK06 offer low voltage operation and rail-to-rail
input and output, as well as excellent speed/power
consumption ratio, providing an excellent bandwidth
(6.5MHz) and slew rate of 3.7V/us. The op-amps are
unity gain stable and feature an ultra-low input bias
current.

(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.
