This datasheet introduces the features of the ADRF6510 dual 6-pole programmable filter and variable gain amplifier, including product overview, features, applications, working principle, circuit diagram, pin diagram, etc.
The ADRF6510 is a matched pair of fully differential low‑noise, low‑distortion programmable filters and variable gain amplifiers (VGAs). Each channel provides a six‑pole Butterworth response from 1 MHz to 30 MHz in 1 MHz steps, continuous gain control from –5 dB to +45 dB, and adjustable output common‑mode voltage.
It is intended for baseband I/Q receivers, diversity receivers, and ADC drivers. The device operates from a single 5 V supply, consumes up to 258 mA at maximum bandwidth, and is available in a 32‑lead LFCSP package. An evaluation board and control software are provided for development.
| Gain control range | −5 dB to +45 dB |
