P2-DAC

Company:

SBS Technologies

Description:

The P2-DAC provides twelve channels of 12-bit digital to analog conversion on a single-wide Type II PC·MIP module. Each channel has a bandwidth of approximately 100 kHz. On power-up the board sets all outputs to zero volts. Channel data is fed to the DACs at any time by the CPU via dual-ported memory. The twelve channels are provided by three four-channel D/A converters. At the maximum conversion rate, all channels are converted simultaneously every 10 us for a maximum board throughput of 1200 kconversions/sec. The D/A converters can run continuously, under software control, or upon receipt of an external strobe pulse. For each trigger source, all twelve channels are converted and settle in less than 10us. The analog output range is fixed at ±10 V nominal. A precision reference supplies all converters with an accurate reference voltage. I/O access is via a front-panel mounted Champ36 female connector. This carries 12 single-ended outputs, an external strobe, and nineteen grounds. The external strobe may trigger conversions if selected by software to do so. Interrupt sources include the external strobe. Data acquisition can be either interrupt event driven or polled. An on-board 16 Kbit EEPROM stores calibration data for each channel and each range. This memory is non-volatile and user-programmable.
