GENERAL DESCRIPTION
The OP162 (single), OP262 (dual), and OP462 (quad) rail-to-
rail 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 applica-
tions 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.
