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 pack-
ages. 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 method-
ology for shutdown. This allows ease of use while reducing
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
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.
