NOTES: (1) Adjustable to zero with external potentiometer. (2) LSB means Least Significant Bit. For ADS7800, 1LSB = 2.44mV for the
±5V range, 1LSB =
4.88mV for the
±10V range. (3) Noise was characterized over temperature near full scale, 0V, and negative full scale. 0.1LSB represents a typical rms level of
noise at the worst case, which was near full scale input at +125
°C. (4) All specifications in dB are referred to a full-scale input, either ±10V or ±5V. (5) For full
scale step input, 12-bit accuracy attained in specified time. (6) Recovers to specified performance in specified time after 2 x FS input overvoltage.

ELECTROSTATIC
DISCHARGE SENSITIVITY
The ADS7800 is an ESD (electrostatic discharge) sensitive
device. The digital control inputs have a special FET struc-
ture, which turns on when the input exceeds the supply by
18V, to minimize ESD damage. However, permanent damage
may occur on unconnected devices subject to high energy
electrostatic fields. When not in use, devices must be stored in
conductive foam or shunts. The protective foam should be
discharged to the destination socket before devices are re-
moved.
