The digital step attenuator uses a single positive 5V supply and has a serial periphery interface (SPITM) for changing attenuation states. This product maintains high attenuation accuracy over frequency and temperature. No external matching components are needed for the DSA. The TQP4M9083 is available in a standard lead-free /green/RoHS-compliant 24-pin 4x4mm QFN package. The TQP4M9071 and TQP4M9072 are also available from TriQuint as a footprint and pin compatible 6-bit, 31.5dB DSA with a parallel control interface and serial control interface respectively.
