  • Eight Single-ended or 3-Wire Differential 20-Bit analog output channels.
  • Simultaneous Clocking; Individual R-2R 20-Bit DAC per output channel.
  • Clocking rates from zero to 500KSPS.
  • Software-selectable fullscale output ranges: ±10V and ±5V; Optionally ±5V and ±2.5V.
  • 256K-sample output FIFO buffer.
  • Low Glitch Impulse; Typically 3.8nV-Sec on ±5V range.
  • Low-Noise DACs and output sections produce 95dB SNR.
  • Clocking from either external or internal sample rate generator.
  • Hardware trigger and clock I/O for multiboard synchronization; Selectable as LVDS or TTL.
  • 8 Bidirectional TTL Digital I/O lines.
  • PCI Express version conforms to PCI Express Specification revision 1.0a for short cards
  • Optional Outputs Disconnect feature supports multiple card redundancy, and ensures quiet outputs during autocalibration and selftest operations.
  • Same pinout as that used for the PCIe-18AO8, with similar software interface.
  • Available also in 16-Channel configuration in full-length format, as well as in PMC and PCI formats
  • DMA Engine supports block-mode and demand-mode transfers.
  • Remote ground sensing to minimize single-ended errors.
  • On-demand autocalibration of all channels.
