Dynamic Measurement System
1
The sink current decreases linearly from 2.8A @ 0 V to 1.2 A @ 15 V. The sink current does not track the programmed current.
2
Following a 30 minute warm-up, the change in output over 8 hours, under constant ambient, load and line operating conditions.
3
For full scale current changes with a risetime of 20 µs, an additional 0.5% error exists in the first data point in the buffer after
the change. The error percentage increases proportionally with the decrease in risetime.
