The WEAOPSLOSP18NI18RO12M22G is a special purpose low offset buffer for bias generator that provides a buffered output for the bandgap voltage.The OpAmp deliberately exhibits systematic offsets to favor near zero Output Voltages. It is Ideal for Power Detector and Temperature sensors with Rail – To – Rail Output that can go down to zero values.
