Rail-to-Rail and Over-the-Top Opamp

The LT1783 rail to rail opamp is an exceedingly robust device. It has reverse battery protection up to 18 V, a common mode input voltage of up to 18 V and protection on the input allowing voltages of –10 V to +24 V relative to the negative supply pin 2 (V–, for most applications at earth potential). With these protective features and its rail-to-rail input and output capability and over-the-top i.e. with one or both its inputs above the positive rail, this device is ideal for current sense applications with the sense resistor either in the supply side or earthside of the current path.
