LMV111 Operational Amplifier with Bias Network
General Description
The LMV111 integrates a rail-to-rail op amp with a V /2 bias circuit into one ultra tiny package, SC70-5 or SOT23-5. The core op amp of the LMV111 is 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 LMV111 reduces external component count. It is a cost effective solution for applications where low voltage operation, low power consumption, space saving, and reliable performance are needed. It enables the design of small portable electronic devices, and allows the designer to place the device closer to the signal source to reduce noise pickup and increase signal integrity.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics. Note 2: Human body model, 1.5k in series with 100pF. Machine model, 0 in series with 100pF.

5V Electrical Characteristics
Note 3: Shorting circuit output to V+
(Continued)
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 TJ(max), JA, and TA. The maximum allowable power dissipation at any ambient temperature is P D = (TJ(max) TA)/JA. 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.
