DESCRIPTION
The LMC8101 is a Rail-to-Rail Input and Output high
performance 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 DSBGA as
well as the 8 pin VSSOP packages. The DSBGA
package requires 75% less board space as compared
to the SOT-23 package. The LMC8101 is an upgrade
to the industry standard LMC7101.
The LMC8101 incorporates a simple user controlled
methodology 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+ or V− using the SL pin (see
Application Notes 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.
