LMV110

LMV101/102/105/110 Fixed-Gain Amplifiers December 1999 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.
