DESCRIPTION
The RS8557, RS8558, RS8559 series of CMOS
operational amplifiers use auto-zero techniques to
simultaneously provide very low offset voltage (20μV
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 4.3MHz and slew rate of 2.5V/μs.
Single or dual supplies as low as +2.7V (±1.35V) and
up to +5.5V (±2.75V) may be used.
The RS8557/RS8558/RS8559 are specified for the
extended industrial and automotive temperature
range (-40°C to 125°C ). The RS8557 single amplifier
is available in 5-lead SOT23, 8-lead MSOP8 and 8-
lead SOIC packages, The RS8558 dual amplifier is
available in 8-lead SOIC and 8-lead MSOP narrow
surface mount packages, the RS8559 quad amplifier
is available in 14-lead SOIC and 14-lead narrow
TSSOP packages.
