Single, 11-V, 50-kHz operational amplifier

The LMC7111 is a micropower CMOS operational amplifier available in the space-saving SOT-23 package. This package makes the LMC7111 an excellent choice for space- and weight-critical designs. The wide common-mode input range enables the design of battery-monitoring circuits that sense signals greater than the V+ supply. The main benefits of the tiny package are most apparent in small, portable, electronic devices, such as mobile phones, pagers, and portable computers. The tiny amplifiers can be placed on a board where needed, simplifying board layout.
