SM5108

Ultra-Small, Low-Cost,

OEM Pressure Die

• For Extremely High-Volume Applications

• 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.

Die are probed, diced, and visually

inspected and shipped on tape in rings.

Custom pressure ranges are available in

high-volume applications.

Minimum order quantities apply to this

product.
