AD8260-EVALZ

大电流驱动器放大器和数字VGA /前置放大器为3 dB步 High Current Driver Amplifier and Digital VGA/Preamplifier with 3 dB Steps

The 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.
