FUNCTIONAL DESCRIPTION
The USB-DA12-8A is an ideal solution for adding portable, easy-to-install analog outputs to any computer with a USB port. The USB-DA12-
8A is a USB 2.0 device, offering the highest speed available with the USB bus. It is fully compatible with both USB 1.1 and USB 2.0 ports.
The board is plug-and-play allowing quick connection whenever you need additional I/O on a USB port.
The USB-DA12-8A features 8 digital-to-analog converters (DACs) with both differential and single-ended outputs on separate connectors.
The board features a variety of unipolar and bipolar ranges for each DAC giving the user a variety of options. The DACs can be updated
individually or simultaneously. To ensure that there will not be excessive outputs to external circuits when the board is plugged in, automatic
circuits limit analog outputs to zero volts. Power is supplied to the board via an external power supply which powers on board DC/DC convert-
ers which provide ±12V to the operational amplifiers on the board. The I/O wiring connections for USB-DA12-8A are via an industry standard,
IDC type 26-pin, 16-pin, and 10-pin connectors.
The USB-DA12-8A is designed to be used in rugged industrial environments but is small enough to fit nicely onto any desk or testing station.
The board is PC/104 sized (3.550 by 3.775 inches) and ships with or without a steel powder-coated enclosure with an anti-skid bottom.
