Multifunction Analog Input Modules

Data Translation Inc has announced the DT9836 series of analog-input multifunction data-acquisition modules for USB 2.0. There are six or twelve 16-bit analog inputs and two 16-bit analog outputs for waveform generation at 500 kHz per channel. Each input has its own A/D converter to eliminate phase shift between channels, a common problem with a multiplexed architecture in which all inputs share one converter. The analog- and digital-subsystem functions are sampled simultaneously to yield a data throughput of 225 kHz per channel; all subsystems operate synchronously at 36 MHz. The DT9836 includes 16 digital inputs and outputs, two 32-bit counter-timers, three quadrature decoders, and a USB 2.0 interface for transferring data at rates up to 480 Mbits/s. The device provides 500-V isolation.
