AD8260 Datasheet (Analog Devices) - High Current Driver Amplifier and Digital VGA/Preamplifier

AD8260, High Current Driver Amplifier and Digital VGA/Preamplifier

The AD8260 includes a high current driver, usable as a transmitter, and a low noise digitally programmable variable gain amplifier (DGA), useable as a receiver.

The receiver section consists of a single-ended input preamplifier, and linear-in-dB, differential-output DGA.

The receiver has a small sig
