NOTES

1Angular accuracy includes offset and gain errors. Stationary digital input and maximum analog frequency inputs.

2Included in the angular error is an allowance for the additional error caused by the phase delay as a function of input frequency. For example, if

fINPUT = 600 Hz, the contribution to the error due to phase delay is: 650 ns × fINPUT × 60 × 360 = 8.4 arc minutes.

3Output subject to input voltage and gain.

Specifications in boldface are production tested.

Specifications subject to change without notice.

CAUTION

1. Absolute Maximum Ratings are those values beyond which

damage to the device may occur.

2. Correct polarity voltages must be maintained on the +VDD

and –VSS pins.

CAUTION

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 AD2S100 features proprietary ESD protection circuitry, permanent damage may

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

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