The OP162 (single), OP262 (dual), and OP462 (quad) rail-torail 15 MHz amplifiers feature the extra speed new designs
require, with the benefits of precision and low power operation.
With their incredibly low offset voltage of 45 µV (typical) and
low noise, they are perfectly suited for precision filter applications and instrumentation. The low supply current of 500 µA
(typical) is critical for portable or densely packed designs. In
addition, the rail-to-rail output swing provides greater dynamic
range and control than standard video amplifiers.
These products operate from single supplies as low as 2.7 V to
dual supplies of ±6 V. The fast settling times and wide output
swings recommend them for buffers to sampling A/D converters.
The output drive of 30 mA (sink and source) is needed for
many audio and display applications; more output current can
be supplied for limited durations. The OPx62 family is specified
over the extended industrial temperature range (–40°C to
+125°C). The single OP162 amplifiers are available in 8-lead
SOIC, MSOP, and TSSOP packages. The dual OP262 amplifiers
are available in 8-lead SOIC and TSSOP packages. The quad
OP462 amplifiers are available in 14-lead, narrow-body SOIC
and TSSOP packages.

For supply voltages greater than 6 V, the input voltage is limited to less than
or equal to the supply voltage.
For differential input voltages greater than 0.6 V, the input current should be
limited to less than 5 mA to prevent degradation or destruction of the input
devices.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operation section
of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
