From cee211f4e5a0f70ee0c202e9a5fc8eac0b9b4945 Mon Sep 17 00:00:00 2001 From: Paul Cercueil Date: Thu, 30 May 2019 16:18:11 +0300 Subject: iio: amplifiers: ad8366: Add support for the ADA4961 DGA This change adds support for the ADA4961 BiCMOS RF Digital Gain Amplifier, (DGA), which is optimized for driving heavy loads out 2.0 GHz and beyond. The device typically achieves -90 dBc IMD3 performance at 500 MHz and -85 dBc at 1.5 GHz. Datasheet link: http://www.analog.com/media/en/technical-documentation/data-sheets/ADA4961.pdf This change re-uses the existing ad8366 driver, as most logic is similar. Also, this chip has a reset pin which is initialized during probe.
