DESCRIPTION
The LMC7111 is a micropower CMOS operational
amplifier available in the space saving SOT-23
package. This makes the LMC7111 ideal for space
and weight critical designs. The wide common-mode
input range makes it easy to design battery
monitoring circuits which sense signals above 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 they are needed, simplifying board
layout.
