AC PERFORMANCE CHARACTERISTICS
With the exception of total harmonic distortion + noise (THD + N) and signal-to-noise (SNR) ratio, these characteristics are included for
design guidance only and are not subject to test. THD + N and SNR are 100% tested.

For 16-bit resolution, 1 LSB = 0.0015% of FSR. 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.
Gain 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.
Gain error is measured with fixed 50 Ω resistors as shown in the Theory of Operation section. Eliminating these resistors increases the gain error by 0.25% of FSR
(unipolar mode) or 0.50% of FSR (bipolar mode).
DAC 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.
External current is defined as the current available in addition to that supplied to REF IN and SPAN/BIPOLAR OFFSET on the AD660.
Operation 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 Use
section.
