2) MAX1459 Reference Manual, which describes in

detail the architecture and functionality of the

MAX1459. This manual was developed for test engi-

neers familiar with data acquisition of sensor data

and provides sensor compensation algorithms and

test procedures.

3) MAX1459 Communication Software, which enables

programming of the MAX1459 from a computer (IBM

compatible), one module at a time.

4) Interface Adapter and Cable, which allow the con-

nection of the evaluation board to a PC parallel port.

MAX1459

Pilot Production System

Maxim understands that one of the biggest challenges

in pressure sensor design is the transition from proto-

type to production. To simplify this transition, Maxim

has developed the fully automated pilot production

system for volume applications.

The system consists of the Maxim 14XXDASBOARD

plus one or more 14XXMUXBOARD modules, a DVM,

an environmental chamber, and a pressure controller.

Only the 14XXDASBOARD and the 14XXMUXBOARD

modules are available through Maxim. The DVM, envi-

ronmental chamber, and pressure controller must be

acquired through other vendors.

The 14XXDASBOARD, in conjunction with the

14XXMUXBOARD modules, allow compensation of up to

112 units. IEEE-488 commands select the active DUT

and communicate with the MAX14XX application cir-

cuits. All system voltage measurements are multiplexed

for use with a single external DVM. Each DUT interfaces

to the 14XXMUXBOARD by means of a general-purpose

transition board, which provides digital interface signals

and low-noise analog inputs. The 14XXDASBOARD is

required to operate the 14XXMUXBOARD. All driver soft-

ware is incorporated into the 14XXDASBOARD firmware.

Sensor compensation procedure is implemented using

National Instruments’ LabView™ program.
