General Description
The MAX5725A evaluation kit (EV kit) demonstrates
the MAX5725A 12-bit, 8-channel, low-power DAC with
selectable internal references and buffered voltage out-
put. The IC is in a 20-pin TSSOP package. The EV kit
provides control to change the DAC’s outputs, power
operations, references, and watchdog time setting.
The IC features a watchdog function that can be enabled
to monitor the I/O interface for activity and integrity.
The EV kit includes a USB-to-SPI interface circuit. The
EV kit features Windows XP^M-, Windows Vista^M-, and
Windows^M 7-compatible software that provides a simple
graphical user interface (GUI) for exercising the IC’s
features.
The EV kit comes with the MAX5725AAUP+ installed,
which is the 12-bit SPI version. Contact the factory for
samples of the pin-compatible MAX5723AUP+ (8-bit),
MAX5724AUP+ (10-bit), and MAX5725BAUP+ (12-bit)
versions.
