  • Page 12: Product Overview

    2. PRODUCT OVERVIEW 2.1 Overview The DAC128V is a singlewide IP Module board, conforming both mechanically and electrically to the ANSI VITA/4-1995, American National Standard for IP Modules. For a typical IP Module carrier that holds four IP Modules, it can provide up to 32 channels of DACs for a single slot on a computer bus backplane, or be mixed with other IP Modules for a more customized, modular I/O system solution.

  • Page 16: Dac's Voltage Ranges

    The following description provides the user with the information necessary to properly set the voltage output ranges for the DACs on the DAC128V. In general, there are three high-side reference voltage levels and three low-side reference voltage levels per group of four DAC outputs.

    25°C, the minimum supply voltage is about +11 V, with it increasing to about +11.5 V for the low temperature operations of the DAC128V, and down to about +10.5 V for the high temperature end. The reference generator’s power supply connections are identical to those of the remaining analog circuitry, and are switched to the externally supplied power sources when jumpered to do so (see section 2.9, below).

    N_ACK 11 ns There is one additional note to add concerning DAC128V IP Module operations. Normally, an IP Module does not drive the IPDbus to a low impedance state until (and during) its assertion of N_ACK during HOLD and termination cycles. To date, this policy has been faithfully followed in the design of all Systran’s IP Modules.

  • Page 31: Maximum Loads

    PERFORMANCE 4.5 Maximum Loads The specification sheet for the DACs used on the DAC128V cites that the maximum current output for all analog channels is ±5 mA. However, a curve near the end of the data sheet presents information that indicates that the maximum capacity should be slightly over ±20 mA per channel.

  • Page 32: Table 4-4 Maximum Currents

    CAUTION: The mean for the last fourteen samples is 20.97857 mA with a standard deviation of 0.38946 mA. Note that this last test shows some droop near the positive rail. Therefore, use the DAC128V with loads exceeding ±5 mA with caution, after conducting capacity testing.

  • Page 33: Beyond Temperature

    For each of five temperature points, 64 DAC voltage output readings and 16 reference voltage outputs were recorded with no load applied. The shortened table is presented to provide the user assurance that the DAC128V can handle wide temperature extremes while maintaining a high degree of accuracy.

  • Page 34: Slew Time Tests

    PERFORMANCE 4.7 Slew Time Tests While the specification sheet indicates that the DAC128V outputs typically settle within 6 µs, and ramp at a rate of 2.2 V/µs, the parameters are not always representative of those that may be encountered in practical applications.
