ROUNDUP
This review of sensors featured recently in Arrow Innovation
highlights two pressure sensors from Infineon, Vishay’s single
and dual channel SMT optical sensors and accelerometer and
yaw rate sensor technologies from Analog Devices.
Analog Devices’ iSensor™ products are highly integrated, calibrated,
motion sensing products that are easy to use and cost-effectively
improve product precision, response time, reliability, safety and
security. The ADIS16350/ADIS16355 iSensor is a complete digital
inertial sensing system that combines a triple-axis gyroscope and
accelerometer. The sensor combines Analog Devices’ iMEMS®
and mixed signal processing technology in a highly integrated,
calibrated solution.

Analog Devices’ ADIS16100 is a yaw detector particularly suitable
for defence and aerospace applications. Surface-micromachining
technology makes a functionally complete yaw rate sensor that
communicates via an integrated SPI. The device produces a digital
output proportional to the angular rate about a defined axis. Using
a single external resistor can increase the measurement range and
a capacitor can reduce the bandwidth.

8.2mm × 8.2mm × 5.2mm package
Infineon’s pressure sensors serve tyre pressure and engine
management needs, combining high precision and low cost
with reliability. The SP 30 is a third generation, single package,
tyre pressure sensor containing a microcontroller, LF receiver and
accelerometer. Its flexibility and high level of integration reduce
system cost while permitting a high degree of customisation.

U
Temperature sensor: -40°C to +125°C
U
Supply voltage sensor: 1.8V to 3.6V
U
Acceleration sensor: -12g to 115g
