Description
The OK8551,OK8552,OK8554,OK8553(dual version
&shutdown)series of CMOS operational amplifiers
use auto-zero techniques to simultaneously provide
very low offset voltage (5μV max) and near-zero drift
over time and temperature. This family of amplifiers
has ultralow noise, offset and power.
This miniature, high-precision operational amplifiers
offset high input impedance and rail-to-rail input and
rail-to-rail output swing. With high gain-bandwidth
product of 4.5MHz and slew rate of 2.7V/μs.
Single or dual supplies as low as +2.7V(±1.35V) and
up to +5.5V (±2.75V) may be used.
The OK8551/OK8552/OK8554/OK8553(dual version
with shutdown) are specified for the extended
industrial and automotive temperature range (-40°C
to 125°C). The OK8551 single amplifier is available in
8-lead MSOP8 and 8-lead SOIC packages, The
OK8552 dual amplifier is available in 8-lead SOIC and
8-lead TSSOP narrow surface mount packages, The
OK8553(dual version with shutdown) comes in Micro-
SIZE MSOP-10. The OK8554 quad is available in 14-
lead SOIC and 14-lead narrow TSSOP packages.
