MAX1459
placed close to the pressure sensor, can cause exces-
sive errors. Of particular concern is an extremely long
sensor-output settling time.
Nonlinearity Compensation
RTEMP can be used in conjunction with RISRC and
RFTC to compensate for sensor nonlinearity. For more
information on this application, refer to the MAX1459
Reference Manual.
Test System Configuration
The MAX1459 is designed to support an automated
production pressure-temperature test system with inte-
grated calibration and temperature compensation.
Figure 15 shows the implementation concept for a low-
cost test system capable of testing multiple transducer
modules connected in parallel. Three-state outputs on
the MAX1459 allow for parallel connection of transduc-
ers. A digital multiplexer controls the chip-select signal
for each transducer. The test system shown in Figure
15 includes a dedicated test bus consisting of five
wires:
Two power-supply lines
One analog output voltage line from the transducers
to a system DVM
Two serial-interface lines: DIO (input/output) and
SCLK (clock)
MAX1459 Evaluation
____________________________________Development Kit
To expedite the development of MAX1459-based trans-
ducers and test systems, Maxim has produced the
MAX1459 evaluation kit (EV kit). First-time users of
the MAX1459 are strongly encouraged to use this
kit. The MAX1459 EV kit is designed to facilitate manu-
al programming of the MAX1459 and includes the fol-
lowing:
1) Evaluation Board with a silicon pressure sensor.
