LMC8101
Rail-to-Rail Input and Output, 2.7V Op Amp in
micro SMD package with Shutdown
General Description
The LMC8101 is a Rail-to-Rail Input and Output high perfor-
mance CMOS operational amplifier. The LMC8101 is ideal
for low voltage (2.7V to 10V) applications requiring Rail-to-
Rail inputs and output. The LMC8101 is supplied in the die
sized micro SMD as well as the 8 pin MSOP packages. The
micro SMD package requires 75% less board space as
compared to the SOT23-5 package. The LMC8101 is an
upgrade to the industry standard LMC7101.
The LMC8101 incorporates a simple user controlled meth-
odology for shutdown. This allows ease of use while reduc-
ing the total supply current to 1nA typical. This extends
battery life where power saving is mandated. The shutdown
input threshold can be set relative to either V
the SL pin (see Application Note section for details).
Other enhancements include improved offset voltage limit,
three times the output current drive and lower 1/f noise when
compared to the industry standard LMC7101 Op Amp. This
makes the LMC8101 ideal for use in many battery powered,
wireless communication and Industrial applications.
