Part Number Junction Temp. Range Package MIC7111BM5 –40 °C to +85°C SOT-23-5 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.

All limits guaranteed by testing on statistical analysis. Note 1: 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. Note 2: I/O Pin Voltage is any external voltage to which an input or output is referenced. Note 3: The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(max); the junction-to-ambient thermal resistance, θJA; and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using: PD = (TJ(max) – TA) ÷ θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature. Note 4: Thermal resistance, θJA, applies to a part soldered on a printed-circuit board. Note 5: Human body model, 1.5k in series with 100pF. Note 6: Short circuit may cause the device to exceed maxium allowable power dissipation. See Note 3.
