Product Description

The RF2371 is a general purpose, low-cost, high performance low noise amplifier designed for operation from a 2.7V to 4V supply with low current consumption. The attenuation of the device is controlled when in power down mode, providing a known gain step. The RF2371 is available in a small industry-standard SOT23-8 surface mount package, enabling compact designs which conserve board space. The design features a highly accurate PTAT (Proportional To Absolute Temperature) biasing scheme using bandgap cells.
