Specifications
Voltage 4.75 to 5.25 V Î (dc) @ 300 mA maximum
Current 210 mA typical @ 20 V Î (dc) out
Absolute Maximum Common
Mode Voltage Measured between output terminals and controller common:
1000V
Resolution
15 bits (plus polarity bit for voltage outputs)
(0.305 mV for 10V output range)
(0.00061 mA for 20 mA output range)
Accuracy (Calibrated for Voltage
Output) For voltage output: ± 0.005V (0.05% at full scale)
For current output: ± 0.1 mA (0.5% at full scale)
Temperature coefficient 440 ppm/ °C typical
Isolation Breakdown Voltage 1000V between input power and signals
Current 0 to 20 mA (500 Ω load max.)
Voltage 0 to 10V Î (dc) with 10 mA source capability
Output Response Time 1 ms typical
Update Rate
Once per controller A/D cycle nominal. Twice per second
maximum for 60 Hz clock rate.
Output changes are step changes due to the fast time con-
stant. All Serial DAC loop outputs are updated at the same
time.
