LMV101 Fixed-Gain Amplifiers

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-powe.
