Analog Output Specifications
Data
4mA maximum to dc COM
Open collector or HC CMOS logic levels
Clock
0.5mA max to dc COM
Open collector or HC CMOS logic levels
Maximum Clock Rate
10 kHz (333 updates/second)
Voltage
4.75 to 5.25Vdc @ 300mA max
Current
210mA typical @ 20Vdc out
Absolute Maximum
Common Mode Voltage
Measured between output pins and controller
common: 1000V
Resolution
15 bits (plus polarity bit for voltage outputs)
(0.305mV for 10V output range)
(0.00061mA for 20mA output range)
Accuracy (calibrated for
voltage output)
For voltage output:
± 0.005V (0.05% at full scale)
For current output: +/ 0.1mA (0.5% at full scale)
Temperature coefficient
440 ppm/ °C typical
Isolation Breakdown
Voltage
1000V between input power and signals
Current
0-20mA (500 Ohm load max.)
Voltage
0-10Vdc with 10mA 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 constant. All SDAC loop outputs are
updated at the same time.
