ZX76-15R5A-PPS+ is a 5-bit digital step attenuator with parallel control and single positive supply voltage input. Attenuation can be set from 0 to 15.5 dB in 0.5 dB steps, with 0.1 dB typical accuracy. The attenuator is housed in a compact unibody package, with SMA RF connections and a snap-fit control input.

The high speed parallel control interface supports manual control and integration with a wide range of microcontroller and custom I/O (input / output) control systems. Data is entered into the internal 5-bit register using 5V logic levels and then latched to set the attenuation.
