Product Description
The RF2451 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 RF2451 is available in a small industry-standard MSOP-8 surface mount package, enabling compact designs which conserve board space. The design features accurate PTAT (Proportional To Absolute Temperature) biasing scheme using band gap cells.
