Available Software Drivers and Software Tools:

The CPCI-DA16 is supported by ALPHI Technology under Windows NT by a Board Support Package which is supplied with the card.

Applications:

The CPCI-ADDA supports P.I.D. loop closure frame rates of up to 4 KHz per channel. The CPCI host can download gain and setpoint changes on the fly. The CPCI host can read back the current values for feedback, error, set-point, and output drive on each channel.

The local DSP processor can be used for data processing such as digital filters and FFTs. The DSP can also be used as a waveform generator to drive the 16-bit DAC.

PCI Bus Controller Features:

• • • Uses the AMCC S5935 PCI controller

    • Supports Windows NT service pack 2 & 3
    • PCI bus operation DC to 33 MHz
    • Four definable pass-through data channels
    • Two 32-byte internal FIFOs with DMA
    • Four mailbox registers with byte-level status and data strobe/interrupts
    • Direct PCI and add-on interrupt pins
    • Serial nvRAM interface or byte-wide nonvolatile memory interface
    • Performs Big Endian/Little Endian conversion

TI DAC712UB D/A Specifications:

• • • 16-channel, 16-bit D/A
    • Voltage output ±10 V
    • Binary 2’s Complement Format
    • DAC712 has a precision +10V temperature-compensated voltage reference
    • The digital interface is fast, 60ns minimum write pulse width, is double-buffered, and has a CLEAR function that resets the analog output to bipolar zero.
    • GAIN and OFFSET adjustment inputs are arranged so that they can be easily trimmed by external D/A converters as well as by potentiometers.
    • The DAC712 is specified at power supply voltages of ±12V and ±15V.
