Features Tiny 5-Pin SOT23 package saves space Very wide common mode input range Specified at 2.7V, 5V, and 10V Typical supply current 25 µA at 5V 50 kHz gain-bandwidth at 5V Similar to popular LMC6462 Output to within 20 mV of supply rail at 100k load Good capacitive load drive 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 designs. 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. Applications Mobile communications Portable computing Current sensing for battery chargers Voltage reference buffering Sensor interface Stable bias for GaAs RF amps

LMC7111BIM5	P2CMOS	0	50860	0	1	4503500	2	578995367
LMC7111BIM5X	P2CMOS	0	50860	0	1	4503500	2	578995367

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
