Manufacturer Part Number
mic914
Description
Mmic914 160mhz Low-power Sot-23-5 Op Amp
Manufacturer
Micrel Semiconductor
Datasheet
General Description
The MIC914 is a high-speed, operational amplifier with a
gain-bandwidth product of 160MHz. The part is unity gain
stable provided its output is loaded with at least 200Ω. It
has a very low 1.25mA supply current, and features the
IttlyBitty
Supply voltage range is from ±2.5V to ±9V, allowing the
MIC914 to be used in low-voltage circuits or applications
requiring large dynamic range.
The MIC914 is stable driving any capacitive load and
achieves excellent PSRR, making it much easier to use
than most conventional high-speed devices. Low supply
voltage, low power consumption, and small packing make
the MIC914 ideal for portable equipment. The ability to
drive capacitive loads also makes it possible to drive long
coaxial cables.
