For 15-bit resolution, 1 LSB = 0.003% of FSR. For 14-bit resolution, 1 LSB = 0.006% of FSR. FSR stands for Full-Scale Range and is 10 V in a Unipolar Mode and 20 V in Bipolar Mode. 2Gain error and gain drift are measured using the internal reference. The internal reference is the main contributor to gain drift. If lower gain drift is required, the AD660 can be used with a precision external reference such as the AD587, AD586 or AD688. 3Gain Error is measured with fixed 50 Ω resistors as shown in the Application section. Eliminating these resistors increases the gain error by 0.25% of FSR (Unipolar mode) or 0.50% of FSR (Bipolar mode). 4DAC Gain Error and Drift are measured with an external voltage reference. They represent the error contributed by the DAC alone, for use with an external reference. 5External current is defined as the current available in addition to that supplied to REF IN and SPAN/BIPOLAR OFFSET on the AD660. 6Operation on ±12 V supplies is possible using an external reference such as the AD586 and reducing the output range. Refer to the Internal/External Reference section. *Indicates that the specification is the same as AD660AN/AR/SQ. Specifications subject to change without notice. REV. A –2– |
