MIC911

105MHz Low-Power SOT-23-5 Op Amp

General Description

The MIC911 is a high-speed operational amplifier which is

unity gain stable regardless of resistive and capacitive load.

It provides a gain-bandwidth product of 105MHz, a very low

package.

Supply voltage range is from

±2.5V to ±9V, allowing the

MIC911 to be used in low-voltage circuits or applications

requiring large dynamic range.

The MIC911 is stable driving any capacitative load and

achieves excellent PSRR and CMRR, making it much easier

to use than most conventional high-speed devices. Low

supply voltage, low power consumption, and small packing

make the MIC911 ideal for portable equipment. The ability to

drive capacitative loads also makes it possible to drive long

coaxial cables.
