NOTES
1The digital input specifications are 100% tested at +25°C, and guaranteed but not tested over the full temperature range.
2Adjustable to zero.
3FSR means “Full-Scale Range” and is 20 V for ±10 V range and 10 V for the ±5 V range.
4A minimum power supply of ±12.5 V is required for a ±10 V full-scale output and ±11.4 V is required for all other voltage ranges.
Specifications subject to change without notice.
