MIC913
350MHz Low-Power SOT23-5 Op Amp
General Description
The MIC913 is a high-speed, operational amplifier. It pro-
vides a gain-bandwidth product of 350MHz with a very low,
4.2mA supply current, and features the tiny SOT-23-5
package.
Supply voltage range is from ±2.5V to ±9V, allowing the
MIC913 to be used in low-voltage circuits or applications
requiring large dynamic range.
The MIC913 requires a minimum gain of +2 or –1 but is
stable driving any capacitive load and achieves excellent
PSRR, making it much easier to use than most conven-
tional high-speed devices. Low supply voltage, low power
consumption, and small packing make the MIC913 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.
