Ultra-Small, Low Cost OEM Pressure Die
DESCRIPTION
The SM5108 is a extremely small (0.65 mm
x 0.65 mm) silicon micromachined
piezoresistive pressure sensing chip that
has been optimized to provide the highest
possible accuracy for a die of this size. This
performance is achieved through careful
resistor placement and mechanical
configuration. The small die results in a
significant cost saving when compared to
larger sensor die. Over 24,000 die come on
a 150 mm wafer.
This sensor is intended for high volume
applications where cost is a critical factor,
such as consumer tire pressure gauges or
disposable pressure gauges. The SM5108 is
available as an absolute pressure sensor in
full-scale ranges of 15 PSI, 30 PSI, 60 PSI,
and 150 PSI. It is designed to be mounted
on ceramic or PC board substrates by high-
volume OEM manufacturers.
