Product Description

The RFSA2614 is a 6-bit Digital Step Attenuator (DSA) that features high linearity

over the entire 31.5dB gain control range with excellent step accuracy in 0.5dB

steps. The parallel-controlled RFSA2614 has an on-chip decoder that is both 3V

and 5V compatible. It also offers a rugged Class 1B HBM ESD rating via on-chip

ESD circuitry.
