Analog Devices ADRF6516 Dual Programmable Filter and Variable Gain Amplifier Datasheet
The ADRF6516 from Analog Devices combines two fully differential programmable filters with variable gain amplifiers (VGAs) in a single 32‑lead LFCSP package. It offers a six‑pole Butterworth response from 1 MHz to 31 MHz in 1 MHz steps, continuous gain control of 50 dB, and digital gain control of 15 dB, making it suitable for IQ receivers, diversity receivers, ADC drivers, and medical instrumentation.
The device operates from a single 3.15 V‑3.45 V supply, draws up to 360 mA at the highest bandwidth, and provides differential input impedance of 1600 Ω and output impedance of 30 Ω. SPI programming configures filter corners, gain steps, and offset‑compensation loops, while the part includes built‑in dc‑offset compensation and a power‑down feature.
