The GRF6402W is a SPI-controlled, bi-directional, 31.75 dB range digital step attenuator which provides precise stepping in 0.25 dB increments. The device’s serial interface utilizes three externally defined address bits, allowing up to 8 unique devices to share a common SPI bus. In addition to supporting traditional serial programming, the GRF6402W also includes a special Rapid Fire selection pin which allows the device to be immediately switched into a pre-defined attenuation state.
