AD698

NOT ES

¹A and B represent the Mean Average Deviation (MAD) of the detected sine waves V_Aand V_B. T he polarity of V_OUTis affected by the sign of the A comparator, i.e.,

multiply V_OUT× +1 for A_COMP+> A_COMP–, and V_OUT× –1 for A_COMP–> A_COMP+

²Nonlinearity of the AD698 only in units of ppm of full scale. Nonlinearity is defined as the maximum measured deviation of the AD698 output voltage from a

straight line. T he straight line is determined by connecting the maximum produced full-scale negative voltage with the maximum produced full-scale positive voltage.

³See T ransfer Function.

⁴For example, if the excitation to the primary changes by 1 dB, the gain of the system will change by typically 100 ppm.

⁵Output ripple is a function of the AD698 bandwidth determined by C1 and C2. A 1000 pF capacitor should be connected in parallel with R2 to reduce the output

ripple. See Figures 7, 8 and 13.

⁶R1 is shown in Figures 7, 8 and 13.

⁷Excitation voltage drift is not an important specification because of the ratiometric operation of the AD698.

⁸From T _MINto T _MAXthe overall error due to the AD698 alone is determined by combining gain error, gain drift and offset drift. For example, the typical overall

error for the AD698AP from T _MINto T _MAXis calculated as follows: Overall Error = Gain Error at +25°C (±0.2% Full Scale) + Gain Drift from –40°C to +25°C

(20 ppm/°C × 65°C) + Offset Drift from –40°C to +25°C (5 ppm/°C × 65°C) = ±0.36% of full scale. Note that 1000 ppm of full scale equals 0.1% of full scale.

Specifications subject to change without notice.

Specifications shown in boldface are tested on all production units at final electrical test. Results from those tested are used to calculate outgoing quality levels.

All min and max specifications are guaranteed, although only those shown in boldface are tested on all production units.

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily

accumulate on the human body and test equipment and can discharge without detection.

Although the AD698 features proprietary ESD protection circuitry, permanent damage may

occur on devices subjected to high energy electrostatic discharges. T herefore, proper ESD

precautions are recommended to avoid performance degradation or loss of functionality.
