MIC914
160MHz Low-Power SOT23-5 Op Amp
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
®
SOT-23-5 package.
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.

Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. Exceeding the maximum differential input voltage will damage the input stage and degrade performance (in particular, input bias current is likely to
change).
4. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
