Overview
The ADRF5731BCCZN-R7 is a silicon, 4-bit digital attenuator produced by Analog Devices Inc. This device offers a 30 dB attenuation control range in 2 dB steps and operates over a wide frequency range from 100 MHz to 40 GHz. It is designed for applications requiring precise RF signal attenuation and features a dual supply voltage of +3.3V and -3.3V. The attenuator is controlled via serial peripheral interface (SPI) or parallel mode, and it is compatible with CMOS/LVTTL logic. The device is packaged in a 16-terminal land grid array (LGA) and is RoHS compliant.
