REF194ESZ

REF194 is a precision micropower low dropout voltage (LDV) reference. It has a precision band gap voltage reference which uses a patented temperature drift curvature correction circuit and laser trimming of highly stable, thin-film resistors to achieve a very low temperature coefficient and high initial accuracy. It is mainly used in application such as portable instruments, ADCs and DACs, smart sensors, solar powered applications, loop-current-powered instruments.
