LMV101/102/105/110

Fixed-Gain Amplifiers

General Description

The LMV101/102/105/110 fixed-gain amplifier family integrates a rail-to-rail op amp, two internal gain-setting resistors and a V+/2 bias circuit into one ultra tiny package, SC70-5 or SOT23-5. Fixed inverting gains of −1, −2, −5, and −10 are available.

The core op amp in this series 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 LMV101/102/105/110 family reduces external component count. It is the most cost effective solution for applications where low voltage operation, low power consumption, space savings, 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, 1.5kΩ in series with 100pF. Machine model, 0Ω in series with 100pF.

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 TJ(max) , θJA, and TA. The maximum allowable power dissipation at any ambient temperature is P D = (TJ(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: Number specified is the slower of the positive and negative slew rates.
