The ADMV8526-EVALZ incorporates the ADMV8526 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 genera- tor and LDO regulators allow the ADMV8526 to be powered by either the 5 V USB supply voltage from the PC via the SDP-S or by using two external power supplies. The ADMV8526 is an IC that features a digitally selectable frequen- cy 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 ADMV8526 through the Analog Figure 1.
