Operational Amplifier
The ISL71218M is a radiation tolerant dual, low-power
Features
precision amplifier optimized for single-supply
Passes NASA low outgassing specifications
applications. This op amp features a common-mode input
- Wide single and dual supply range: 3V to 30V (10%)
voltage range extending to 0.5V below the V rail, a
rail-to-rail differential input voltage range, and
Low current consumption: 850A, typical
rail-to-rail output voltage swing, which makes it ideal for
Low input offset voltage: 40V, typical
single-supply applications where input operation at
ground is important. Rail-to-rail output: <10mV
This op amp features low-power, low-offset voltage, and NiPdAu-Ag lead finish
low-temperature drift, making it ideal for applications
Dielectrically isolated PR40 process
requiring both high DC accuracy and AC performance. It
