NOTES: (1) USB = unipolar straight binary; BOB = bipolar offset binary. (2) TTL, LSTTL and 54/74 HC compatible. (3) Adjustable to zero with external trim potentiometer. (4) Error at input code 00016 for both unipolar and bipolar ranges. (5) FSR means full scale range and is 20V for the ±10V range. (6) Maximum represents the 3 σ limit. Not 100% tested for this parameter. (7) At the major carry, 7FF 16 to 80016 and 80016 to 7FF16. (8) Minimum supply voltage required for ±10V output swing is ±13.5V. Output swing for ±11.4V supplies is at least –8V to +8V. (9) The maximum voltage at which ACOM and DCOM may be separated without affecting accuracy specifications. SPECIFICATIONS At TA = +25°C. ±VCC = 12V or 15V, unless otherwise noted. |
