The RF2451 is a general purpose, low-cost, high perfor-
mance 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 con-
serve board space. The design features accurate PTAT
(Proportional To Absolute Temperature) biasing scheme
using band gap cells.
