Isolated Sigma-Delta Modulator fosters precision measurement.

June 3, 2014

Able to achieve 81 dB min signal-to-noise and distortion ratio (SINAD) @ 78 KSPS over -40 to +125°C range, AD7403 promotes current and voltage measurement accuracy in DC/AC power conversion applications and subsequently improves performance of motor drives by reducing torque ripple on motor shaft. SINAD value also increases power transfer efficiency in DC/AC power inverter applications. Modulator employs iCoupler® digital isolation technology and offers 1.5 µV/°C typ offset drift. Read More

Spacial Light Modulators feature plug-and-play design.

August 15, 2013

Using both translucent and reflective liquid crystal micro-display technology, Spatial Light Modulators dynamically modify amplitude and/or phase of incident light. Units individually manipulate each pixel in real-time and include patented technology for eliminating Black-matrix effects and phase calibration. Users can directly connect PC video/graphics to modulators, as well as program units to behave like gratings, lenses, diffractive optical elements, masks, and encryptors.
