NOTES
1
Angular accuracy includes offset and gain errors, measured with a stationary digital input and maximum analog frequency inputs.
2
The angular error does not include the additional error caused by the phase delay as a function of input frequency. For example, if f
INPUT
= 600 Hz, the contribution
to the error due to phase delay is: 650 ns

Output subject to input voltage and gain.
Specifications subject to change without notice.
WARNING!
ESD SENSITIVE DEVICE
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 AD2S105 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.
