Description
Mic918 51mhz Low-power Sot-23-5/sc-70 Op Amp
Manufacturer
Micrel Semiconductor
Datasheet
General Description
The MIC918 is a high-speed operational amplifier with a
gain-bandwidth product of 51MHz. The part is unity gain
stable. Ithas a very low 550A supply current, and features
the IttyBitty
Supply voltage range is from 2.5V to 9V, allowing the
MIC918 to be used in low-voltage circuits or applications
requiring large dynamic range.
The MIC918 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 MIC918 ideal for portable equipment.
The ability to drive capacitative loads also makes it pos-
sible to drive long coaxial cables.
