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.
