LMC7111
Tiny CMOS Operational Amplifier with Rail-to-Rail Input
and Output
General Description
The LMC7111 is a micropower CMOS operational amplifier
available in the space saving SOT 23-5 package. This
makes the LMC7111 ideal for space and weight critical de-
signs. 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.
