Dual I/O modules save space, time

A new line of FieldPoint modules permits systems integrators to add two I/O modules at a time. Users can match the number of I/Os to a particular application, creating economical systems with fewer unused or wasted channels. The modules provide both analog and digital I/O capabilities for process control, industrial automation, and product test and validation. National Instruments; www.ni.com

Precision ADC breaks speed barrier

The AD7664 is the first 16-bit successive approximation register analog-to- digital converter to touch and cross the 500 kilosamples/sec mark. The speed allows high-speed data acquisition and many channels to be multiplexed through the converter. It features parallel or serial interfaces, and low signal-to-noise ratio, and is family pin compatible. Analog Devices, Inc.; www.analog.com
