Special Purpose Low offset Operational Amplifier
The WEAOPSLO18NI18RO12M22G is a special purpose low offset and low noise opamp.
Overview
The WEAOPSLO18NI18RO12M22G is a special purpose low offset and low noise opamp. The opamp architecture is two-stage Miller with RC compensation. The opamp provides current outputs that copy the current flowing out of the main opamp output. This feature allows easy poly current generation since the current copied at the current outputs will have a relation of Vref/Rload when the opamp is connected as a unity gain buffer with vref at its positive input. (figure 2). There are two sets of current outputs: general purpose unfiltered outputs and filtered outputs required by low noise circuits.
