The AD8260-EVALZ is an evaluation board for AD8260 IC. This board is shipped fully assembled, tested and provides basic functionality as shipped. Connectors enable the user to connect standard types of lab test equipment without having to wait for the rest of the design to be completed. 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 AD8260 preamplifier (PrA) is configured with external resistors for gains greater than 6 dB and can be inverting or noninverting.
