Product Design and Development

Signal Chain Solution

Analog Devices (Norwood,
MA) has introduced the
CN0267 demonstration
circuit for a loop powered highway
addressable remote transducer (HART)
enabled smart transmitter, for industrial applications that need to operate within a set 3.5-mA
power budget. Features include:
A 7 x 2. 3 cm footprint.

A direct sensor interface, microprocessor, and 2-way HART communication over a 4 to 20 mA loop.

An on-chip ADC0 that measures the field instrument primary sensor.

An analog front-end that incorporates dual high performance 24-bit sigma-delta analog-to-digital converters (ADCs).

Reliability in a Clutch

Capacitive Touch Screens Projected Capacitive Touch Screens from Molex (Lisle, IL) leverage existing capaci- tive switch technology to deliver multi-touch functionality. Features include: An etched conductive layer that senses touch through the protective layers. A use life of up to 200 million actuations. A 10-point, multi-touch capability that allows advanced gesturing functionality. A range of screen design sizes from 2" to 32" in 4,096 x 4,096 dpi resolution.

Availability in glass-and-glass, glass-and-film, and film-and-film screens.

Different glass styles, including general, chemical reinforced, and tempered, as well as surface treatment finishes including anti-glare, anti-reflective, and clear.

Embedded software that can be configured to meet specific electrical output requirements. Multiple output interfaces including USB, I2C, and discrete signals.

Applicability in medical IV pumps, defibrillators, glucose meters, and pulse oximeters; industrial equipment controls and consumer devices such as tablets, hand-helds, and GPS devices.

...a clutch, brake or power transmission part for that matter. Since 1903 Carlyle Johnson has solved some of history’s toughest motion control challenges – it’s what we love to do. Our precision electrical, mechanical, air and hydraulic power transmission products consistently prove reliable and dependable in every application. Underwater, on the ground and in the air, CJM is everywhere.

Fully Isolated A/D Boards United Electronic Industries (UEI) (Walpole, MA) has 4 new analog input boards that provide simultaneous sampling with each channel based on its own oversampled SAR converter. The boards also go into a high impedance mode when power is removed, making them ideal for high reliability, redundant monitoring applications. Features include:

8 analog input channels.

A 24-bit A/D resolution.

120 kilosample/second maximum sampling rates.

Complete 350 Vrms channel-to-channel and channel-to-chassis isolation. A diagnostic input mode that flags open circuited connections and overvoltage conditions. A comprehensive API that supports all popular Windows programming languages. Input gains of 1, 2, 4, 8, 16, 32, and 64 that are fully software programmable.
