Analog Devices Inc. EVAL-ADMV8505 Evaluation Board evaluates the ADMV8505 digitally tunable band-pass filters (BPFs). The ADMV8505-EVALZ incorporates the ADMV8505 chip, as well as a negative voltage generator, low dropout (LDO) regulators, and an interface to the EVAL-SDP-CS1Z (SDP-S) system demonstration platform (SDP) to allow simple and efficient evaluation. The negative voltage generator and LDO regulators enable ADMV8505 to be powered by either the 5V USB supply voltage from the PC via the SDP-S or two external power supplies.
The ADMV8505 is an IC that features a digitally selectable frequency of operation. The chip can be programmed using a 4-wire serial peripheral interface (SPI), and the SDP-S controller allows the user to interface with the SPI of the ADMV8505 through the Analog Devices, Inc., Analysis, Control Evaluation (ACE) software.
