Working Principle

The operation of the LMV1089VY/NOPB is based on a concealed MOSFET output stage. The amplifier is based on a differential transistor pair, which is configured as a current mirror.Current is supplied through the amplifier’s input, and flows through the MOSFETs in the output stage. The two transistors are connected in a cascade configuration, allowing current from the first transistor to switch off the second one. This creates a high-speed voltage-controlled current source in the amplifier’s output stage.The voltage-controlled current source in the amplifier’s output stage allows for high speed, low-power operation, with excellent linearity and low noise. The amplifier has a gain of up to 50dB, and can achieve frequencies up to 2.4GHz. The amplifier also has a wide bandwidth from 5kHz to 2.4GHz, allowing for high-frequency response.
