GENERAL DESCRIPTION
The ADMV8526-EVALZ is available for evaluating the ADMV8526
digitally tunable, band-pass filter (BPF). 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
Devices, Inc.,
Analysis, Control Evaluation
For full details on the ADMV8526, see the ADMV8526 data sheet,
which must be consulted in conjunction with this user guide when
using the ADMV8526-EVALZ.
