MIC7111
1.8V IttyBitty™ Rail-to-Rail Input/Output Op Amp
Final Information
General Description
The MIC7111 is a micropower operational amplifier featuring
rail-to-rail input and output performance in Micrel’s IttyBitty
™
SOT-23-5 package. The MIC7111 is ideal for systems where
small size is a critical consideration.
The MIC7111 is designed to operate from 1.8V to 11V power
supplies.
The MIC7111 benefits small battery operated portable elec-
tronic devices where small size and the ability to place the
amplifier close to the signal source are primary design
concerns.
For other package options, please contact the factory.
Features
Small footprint SOT-23-5 package
Guaranteed performance at 1.8V, 2.7V, 5V, and 10V
15µA typical supply current at 1.8V
25kHz gain-bandwidth at 5V
Output swing to within 1mV of rails
with 1.8V supply and 100kΩ load

General Notes:
Devices are ESD protected; however, handling precautions are recommended. All limits guaranteed by testing on statistical analysis.
Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when
operating the device outside its recommended operating ratings.
I/O Pin Voltage is any external voltage to which an input or output is referenced.
The maximum allowable power dissipation is a function of the maximum junction temperature, T
J(max)
; the junction-to-ambient thermal
resistance,
θ
JA
; and the ambient temperature, T
A
. The maximum allowable power dissipation at any ambient temperature is calculated using:
P
D
= (T
J(max)
– T
A
)
÷
θ
JA
. Exceeding the maximum allowable power dissipation will result in excessive die temperature.
Thermal resistance,
θ
JA
, applies to a part soldered on a printed-circuit board.
Human body model, 1.5k in series with 100pF.
Short circuit may cause the device to exceed maxium allowable power dissipation. See
Note 3.
