LMV111
Operational Amplifier with Bias Network
General Description
The LMV111integrates a rail-to-rail op amp with a V +
/2bias circuit into one ultra tiny package,SC70-5or SOT23-5.The core op amp of the LMV111is an LMV321,which provides rail-to-rail output swing,excellent speed-power ratio,1MHz bandwidth,and 1V/µs of slew rate with low supply current.The LMV111reduces external component count.It is a cost effective solution for applications where low voltage opera-tion,low power consumption,space saving,and reliable per-formance are needed.It enables the design of small portable electronic devices,and allows the designer to place the de-vice closer to the signal source to reduce noise pickup and increase signal integrity.

5V Electrical Characteristics
(Continued)
Note 3:Shorting circuit output to V +will adversely affect reliability.Note 4:Shorting circuit output to V -will adversely affect reliability.
Note 5:The maximum power dissipation is a function of T J(max),θJA ,and T A .The maximum allowable power dissipation at any ambient temperature is P D =(T J(max)–T A )/θJA .All numbers apply for packages soldered directly into a PC board.Note 6:Typical values represent the most likely parametric norm.Note 7:All limits are guaranteed by testing or statistical analysis.
Note 8:Connected as voltage follower with 3V step input.Number specified is the slower of the positive and negative slew rates.
