ISL70218SEH
The ISL70218SEH is a dual, low-power precision amplifier
optimized for single-supply applications. This op amp features
a common mode input voltage range extending to 0.5V below
the V- rail, a rail-rail differential input voltage range, and
rail-to-rail output voltage swing, which makes it ideal for
single-supply applications where input operation at ground is
important.
This op amp features low power, low offset voltage, and low
temperature drift, making it ideal for applications requiring
both high DC accuracy and AC performance. This amplifier is
designed to operate over a single supply range of 3V to 36V or a
split supply voltage range of +1.8V/-1.2V to ±18V. The
combination of precision and small footprint provides the user
with outstanding value and flexibility relative to similar
competitive parts.
Applications for this amplifier include precision
instrumentation, data acquisition and precision power supply
controls.
The ISL70218SEH is available in a 10 lead hermetic ceramic
flatpack and operates over the extended temperature range of
-55°C to +125°C.
