MIC923
Description
410MHz Low-Power SC70 Op Amp
Manufacturer
Micrel Semiconductor
Datasheet
General Description
The MIC923 is a high-speed operational amplifier with a gain-
bandwidth product of 410MHz. The part is unity gain stable.
It has a very low 2.5mA supply current, and features the
Teeny ™SC70 package.
Supply voltage range is from 2.5V to 9V, allowing the
MIC923 to be used in low-voltage circuits or applications
requiring large dynamic range.
The MIC923 requires a minimum gain of +2 or –1 but is stable
driving any capacitive load. It has excellent PSRR and
CMRR, making it much easier to use than most conventional
high-speed devices. Low supply voltage, low power con-
sumption, and small packaging make the MIC923 ideal for
portable equipment. The ability to drive capacitative loads
also makes it possible to drive long coaxial cables.
