MIC920
80MHz Low-Power SC-70 Op Amp
General Description
Features
The MIC920 is a high-speed operational amplifier with a
gain-bandwidth product of 80MHz. The part is unity gain
stable. It has a very low 550µA supply current, and features
the SC-70 package.
Supply voltage range is from ±2.5V to ±9V, allowing the
MIC920 to be used in low-voltage circuits or applications
requiring large dynamic range.
The MIC920 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 MIC920 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.”

Applications Information
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
resis-tance). Surface-mount ceramic capacitors are ideal.
Thermal Considerations
The SC70-5 package and the SOT-23-5 package, like all
small packages, have 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
par-ticular CMRR will reduce.
An MIC920 with no load, dissipates power equal to the quiescent supply current × supply voltage
The MIC920 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 MIC920 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
Conventional op amp gain configurations and resistor selection apply, the MIC920 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, par-ticularly
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.

)
PD(no load) = VV+ – VV- IS
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.
TJ(max) – TA(max)
Max. Allowable Power Dissipation =
