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 AD640 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.
WARNING!
ESD SENSITIVE DEVICE

6. The low input offset voltage of 50
μ
V (200
μ
V max) ensures
good accuracy for low level dc inputs.
7. Thermal recovery “tails,” which can obscure the response
when a small signal immediately follows a high level input,
have been minimized by special attention to design details.
8. The noise spectral density of 2 nV/
√
Hz
results in a noise floor of
~23
μ
V rms (–80 dBm) at a bandwidth of 100 MHz. The dy-
namic range using cascaded AD640s can be extended to 95 dB
by the inclusion of a simple filter between the two devices.
