Product Description
RFMD's RFSA2514 is a 5-bit digital step attenuator (DSA) that features high linear-
ity over the entire 15.5dB gain control range with excellent step accuracy in 0.5dB
steps. The RFSA2514 is programmed via a serial mode control interface that is
both 3V and 5V compatible. The RFSA2514 also offers a rugged Class 1C HBM ESD
rating via on-chip ESD circuitry. The MCM package is footprint compatible with most
24-pin, 4mm x 4mm, QFN packages.
