ADRF6516ACPZ-WP

RF Misc ICS And Modules Overview

The ADRF6516ACPZ-WP is a dual-channel, fully differential integrated circuit featuring low-noise programmable filters and variable gain amplifiers (VGAs). It utilizes a 32-lead LFCSP package with an exposed pad. The device operates on a supply voltage ranging from 3.15 V to 3.45 V. Each channel integrates a six-pole Butterworth low-pass filter with a programmable 1 dB cutoff frequency between 1 MHz and 31 MHz in 1 MHz steps. The VGA provides a continuous gain control range of 50 dB. The component supports digital gain control of 15 dB and maintains harmonic distortion performance exceeding 65 dBc for HD2 and HD3, with IMD3 also greater than 65 dBc.
