Specification

* Same as specification for DAC667AH.

NOTES: (1) The digital input specifications are 100% tested at +25°C and over the full temperature range. (2) Adjustable to zero. (3) FSR means full scale range

and is 20V for ±10V range and 10V for the ±5V range (4) ±10V full scale output can be achieved using ±11.4 supplies.
