Datasheet MIC7111 (Microchip)

MIC7111
1.8V to 11V, 15µA, 25kHz GBW, Rail-to-Rail
Input and Output Operational Amplifier General Description Features The MIC7111 is a low-power operational amplifier with railto-rail inputs and outputs. The device operates from a 1.8V
to 11V single supply or an ±0.9V to ±5.5V dual supply. The
device consumes a low 15µA of current from a 1.8V supply
and 25µA from a 10V supply. The device features a unity
gain bandwidth of 25kHz and swings within 1mV of either
the supply rail with a 100kΩ load. The device is capable of
sinking and sourcing 25mA of current from a 1.8V supply
and up to 200mA from a 10V supply. The device is
available in the cost effective SOT23-5 package. •
