Key Features
Four quad-voltage output DACs generate the sixteen analog output channels. Settling times of 10 uSec enable the DACs to produce relatively high-speed output waveforms. The fifty-pin field I/O connector provides the voltage output signals. This connector also terminates two general-purpose digital output signals and the external synchronization signals.
Users can tailor the card’s output voltage for their application, using the card’s four analog output ranges. Bipolar ranges of +/- 10 volts or +/- 5.0 volts and unipolar ranges of 0 to 10 volts or 0 to 5.0 volts are supported. All output ranges provide a minimum of 5 milliamps of output current.
An on board DC to DC converter generates the +/- 15-volt power used by the D to A converters. External power supplies are not required to achieve the full-scale output voltage of +/- 10 volts.
Additional features include board identifier registers, control and status register, external sync signals and DAC loop-back registers.
This board is compatible with the PAS 9890/CAR, a VME carrier for four IP modules, and the PAS 3090/CAR, a PCI Express carrier for three IP modules. It is ideal for a variety of applications including industrial automation, closed-loop servo control, process control, and automotive test and measurement.
Card Features
- 16 channels of analog voltage outputs, with a 12 bit D/A Converter per channel
- Software selectable +/- 10 V, +/- 5V, 0-10V, and 0 to 5V ranges @ 5 mAmp output per channel

- All DACs are calibrated with a precision on board voltage reference
- Offset binary or two’s complement data format software selectable
- DACs reset to bipolar zero during power up reset
- Output slew rate of 2.2 Volts per uSec, Settling time of 10 uSec to 0.01%
- DACs have digital readback registers
- Double buffered DACs can be updated simultaneously with software sync or external sync signal
- TTL level sync in and sync out signals are provided in the I/O connector
- Two general purpose digital output signals provided in the I/O connectors
- Board identifier registers
- Positive and Negative DAC reference voltages are available in the I/O connector
