LMC7111

LMC7111 Tiny CMOS Operational Amplifier with Rail-to-Rail Input and Output August 1999 LMC7111 Tiny CMOS Operational Amplifier with Rail-to-Rail Input and Output General 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. n n n n n n 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 Applications n n n n n n Mobile communications Portable computing Current sensing for battery chargers Voltage reference buffering Sensor interface Stable bias for GaAs RF amps Features n Tiny SOT23-5 package saves space n Very wide common mode input range Connection Diagrams 8-Pin DIP 5-Pin SOT23-5 DS012352-1 DS012352-2 Top View Top View Actual Size DS012352-19 Ordering Information Package 8-Pin DIP 8-Pin DIP 5-Pin SOT23-5 Ordering Information LMC7111AIN LMC7111BIN LMC7111BIM5 NSC Drawing Number N08E N08E MA05A Package Marking LMC7111AIN LMC7111BIN...
