dSPACE DS2004 High-Speed A/D Board
http://www.dspaceinc.com/en/inc/home/products/hw/modular_hardware_introduction/i_o_boards/ds2004_high_speed_a_d_board.cfm

This board has 16 A/D input channels (differential).
Analog input range for each channel is +/-5V or +/-10V.
It has 16 independent A/D converters.
The resolution of each A/D converter is 16-bit.
The conversion time of each A/D channel is 800ns.

Does anyone can guess what is the device in "white" color on the board (see attached image, click the image for enlarged view)? It looks to me that each A/D converter is accompanied by one "white" device.
Is it reed relay? If YES, what is it for?

Here is a link to the manual http://www.dspace.de/shared/data/pdf/flyer2005/dspace-flyer-2005_ds2004_e.pdf

They have "signal conditioning" circuitry according to the manual which is probably what the white devices are, maybe custom hybrids.

Thanks. I think those white ICs may be "difference amplifier"... any white "difference amplifier" or "amplifier" IC in the market?
