45MHz Low-Power SC-70 Op Amp
Final Information
General Description
The MIC921 is a high-speed operational amplifier with a gain-
bandwidth product of 45MHz. The part is unity gain stable. It
has a very low 300µA supply current, and features the
IttyBitty^™ SC-70 and SOT-23-5 package.
Supply voltage range is from ±2.5V to ±9V, allowing the
MIC921 to be used in low-voltage circuits or applications
requiring large dynamic range.
The MIC921 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 MIC921 ideal for portable equipment. The ability to
drive capacitative loads also makes it possible to drive long
coaxial cables.
