Serial DAC Analog Outputs
Table 8.32 Serial DAC Analog Output Specifi-
cations
Absolute Maximum Common
Mode Voltage
Measured between output terminals and controller common:
1000 V
Resolution
15 bits (plus polarity bit for voltage outputs)
(0.305 mV for 10 V output range)
(0.00061 mA for 20 mA output range)
Accuracy (Calibrated for Voltage
Output)
For voltage output: ± 0.005 V (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 1000 V between input power and signals
Current 0 to 20 mA with 10 V minimum compliance (500 Ω load)
Voltage 0 to 10 Vdc 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.
