MIC921
45MHz Low-Power SC-70 Op Amp
Final Information
General Description
Features
The MIC921 is a high-speed operational amplifier with a gainbandwidth 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.

Note 1.
Exceeding the absolute maximum rating may damage the device.
Note 2.
The device is not guaranteed to function outside its operating rating.
Note 3.
Exceeding the maximum differential input voltage will damage the input stage and degrade performance (in particular, input bias current is
likely to change).
Note 4.
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
Note 5.
Output swing limited by the maximum output sink capability, refer to the short-circuit current vs. temperature graph in “Typical Characteristics.”

Power Supply Bypassing
Regular supply bypassing techniques are recommended. A
10µF capacitor in parallel with a 0.1µF capacitor on both the
positive and negative supplies are ideal. For best performance all bypassing capacitors should be located as close to
the op amp as possible and all capacitors should be low ESL
(equivalent series inductance), ESR (equivalent series resistance). Surface-mount ceramic capacitors are ideal.
Thermal Considerations
The SC70-5 package, like all small packages, has a high
thermal resistance. It is important to ensure the IC does not
exceed the maximum operating junction (die) temperature of
85°C. The part can be operated up to the absolute maximum
temperature rating of 125°C, but between 85°C and 125°C
performance will degrade, in particular CMRR will reduce.
An MIC921 with no load, dissipates power equal to the
quiescent supply current * supply voltage
Applications Information
The MIC921 is a high-speed, voltage-feedback operational
amplifier featuring very low supply current and excellent
stability. This device is unity gain stable, capable of driving
high capacitance loads.
Driving High Capacitance
The MIC921 is stable when driving high capacitance, making
it ideal for driving long coaxial cables or other high-capacitance loads. Most high-speed op amps are only able to drive
limited capacitance.
Note: increasing load capacitance does reduce
the speed of the device. In applications where
the load capacitance reduces the speed of the
op amp to an unacceptable level, the effect of
the load capacitance can be reduced by adding
a small resistor (<100Ω) in series with the
output.
Feedback Resistor Selection
(
MIC921
)
PD(no load) = VV + − VV − IS
Conventional op amp gain configurations and resistor selection apply, the MIC921 is NOT a current feedback device.
Also, for minimum peaking, the feedback resistor should
have low parasitic capacitance, usually 470Ω is ideal. To use
the part as a follower, the output should be connected to input
via a short wire.
Layout Considerations
All high speed devices require careful PCB layout. The
following guidelines should be observed: Capacitance, particularly on the two inputs pins will degrade performance;
avoid large copper traces to the inputs. Keep the output signal
away from the inputs and use a ground plane.
It is important to ensure adequate supply bypassing capacitors are located close to the device.
When a load is added, the additional power is dissipated in
the output stage of the op amp. The power dissipated in the
device is a function of supply voltage, output voltage and
output current.

)
PD(output stage) = VV + − VOUT IOUT
Total Power Dissipation = PD(no load) + PD(output stage)
Ensure the total power dissipated in the device is no greater
than the thermal capacity of the package. The SC70-5
package has a thermal resistance of 450°C/W.
