ISL70218SRH
The ISL70218SRH 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, precision power supply
controls, and industrial controls.
The ISL70218SRH is available in a 10 Ld hermetic ceramic
flatpack and operates over the extended temperature range of
-55°C to +125°C.

... The ISL70218SRH is immune to output phase reversal out to 0.5V beyond the rail (V Single Channel Usage The ISL70218SRH is a dual op amp. If the application requires only one channel, the user must configure the unused channel to prevent it from oscillating. The unused channel oscillates if the input and output pins are floating. This results in higher-than-expected supply currents and possible noise injection into the channel being used ...
