MIC922

230MHz Low-Power SC-70 Op Amp

Final Information

General Description

The MIC922 is a high-speed operational amplifier with a gain-

bandwidth product of 230MHz. The part is unity gain stable.

It has a very low 2.5mA supply current, and features the

Teeny™ SC-70 package.

Supply voltage range is from

±2.5V to ±9V, allowing the

MIC922 to be used in low-voltage circuits or applications

requiring large dynamic range.

The MIC922 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 MIC922 ideal for portable equipment. The ability to

drive capacitative loads also makes it possible to drive long

coaxial cables.
