The MAX5893/MAX5894/MAX5895 evaluation kits (EV

kits) are fully assembled and tested circuit boards that

contain all the components necessary to evaluate the per-

formance of this family of interpolating and modulating

dual digital-to-analog converters (DACs). The EV kit

boards include circuitry that converts the DAC differential

output currents to single-ended voltages. The EV kits also

include circuitry that generates a clock signal from an AC

sine-wave input signal.

The included evaluation software runs under Windows

98/2000/XP, providing a graphical user interface (GUI) to

exercise the features of the MAX5893/MAX5894/

MAX5895 through the use of an SPI™ interface.

The MAX5893/MAX5894/MAX5895 EV kits provide a

proven PC board layout to facilitate evaluation of the

MAX5893/MAX5894/MAX5895. The EV kits must be inter-

faced to appropriate timing signals for proper operation.

When using the EV kits without the CMOD232 command

module, connect the system-side power (VMOD), ground-

return (GND), and interface (SCLK, CS, DIN, DOUT) sig-

nals to the pads on the PC board (see Figure 5). Refer to

the MAX5895 data sheet for timing requirements.

The MAX5895 evaluation software runs under Windows

98/2000/XP on an IBM PC, interfacing to the EV system

board (CMOD232) through the computer’s serial commu-

nications port. See the Quick Start section for setup and

operating instructions.

Order the complete EV system for comprehensive

evaluation of the MAX5893/MAX5894/MAX5895 using a

personal computer. Order the EV kit if the command

module has already been purchased with another Maxim

EV system, or for custom use in other microcontroller

(µC)-based systems.

The MAX5893/MAX5894/MAX5895 EV kits can be used

to evaluate the MAX5893 (12-bit), MAX5894 (14-bit),

and the MAX5895 (16-bit) digital-to-analog converters.

See the Ordering Information table for instructions on

how to order the EV kit (and EV system) with these

devices preinstalled.
