Technical Characteristics

• Absolute Maximum Ratings: No external voltage or current must be applied

• Isolation:

  • Between output terminals and internal circuitry: isolated (capacitive coupling), withstands 500 V DC for 1 minute

  • Between output terminals or between output terminals and external power supply: not isolated, common negative

• Output Signal Range (Voltage):

  • –11 to 11 V (default)

  • –0.5 to 10.5 V

  • –0.25 to 5.25 V

  • 0.1 to 5.25 V

• Disabled Output Impedance: 1 MΩ min (100 kΩ if external power off)

• Leakage Current at Disabled Output: ±0.5 µA max

• Allowable Load Resistance:

  • 1 kΩ min (for –10 to 10 V or 0 to 10 V range)

  • 500 Ω min (for 0 to 5 V or 1 to 5 V range)

• Allowable Capacitive Load: 20 nF max

• Output Update Time: 2 µs + 2 µs × (number of channels updated)

  • Example: 4 µs (1 channel), 10 µs (4 channels), 18 µs (8 channels)

• Synchronous Output: DAC of all channels can be updated simultaneously

• Output Response Time: ≤20 µs (–10 to 10 V range, 2 kΩ load)
