Ratiometric Output Configuration
Ratiometric output configuration provides an output that
is proportional to the power-supply voltage. When used
with ratiometric A/D converters, this output provides
digital pressure values independent of supply voltage.
Most automotive and some industrial applications
require ratiometric outputs.
The MAX1478 provides a high-performance ratiometric
output with a minimum number of external components
(Figure 10). These external components include the fol-
lowing:
One power-supply bypass capacitor (C1)
Two optional resistors, one from FSOTC to ISRC, and
another from ISRC to V
SS
, depending on the sensor
type
One optional capacitor (C2) from BDRIVE to V
SS
Test System Configuration
The MAX1478 is designed to support an automated
production pressure-temperature test system with inte-
grated calibration and temperature compensation.
Figure 11 shows the implementation concept for a low-
cost test system capable of testing up to 12 transducer
modules connected in parallel. The test system shown
in Figure 11 includes a dedicated test bus consisting of
four wires:
Two power-supply lines
Two serial-interface lines: DIO (input/output) and
SCLK (clock)
An individual V
OUT
line
For simultaneous testing of more than 12 sensor mod-
ules, use buffers to prevent overloading the data bus. A
digital multiplexer controls the chip-select signal for
each transducer.
