... Figure 43. OP492 Has Fast Overload Recovery for Comparator Applications PROGRAMMABLE PRECISION WINDOW COMPARATOR The OP292/OP492 can be used for precise level detection, such as in test equipment where a signal is measured within a range (see Figure 44). A pair of 12-bit DACs sets the threshold voltage level. The DACs have serial interface, which minimizes interconnection requirements ...
