NOTES

1For A grade only, voltage outputs are guaranteed only if +VS ≥ 7 V and –VS ≤ –7 V.

2Specified using external op amp, see Figure 3 for more details.

3Tested at full-scale input.

4For A grade only, power supplies must be symmetric, i.e., VS = |–VS| and +VL = |–VL|. Each supply must independently meet this equality within ± 5%.

All min and max specifications are guaranteed. Specifications in boldface are tested on all production units at final electrical test. Results from those tests are used to

calculate outgoing quality levels.

Specifications subject to change without notice.

*Stresses greater than those listed under “Absolute Maximum Ratings” may cause

permanent damage to the device. This is a stress rating only and functional

operation of the device at these or any other conditions above those indicated in

the operational section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect device reliability.

ESD SENSITIVITY

The AD766 features input protection circuitry consisting of large “distributed” diodes and

polysilicon series resistors to dissipate both high energy discharges (Human Body Model) and

fast, low energy pulses (Charged Device Model). Per Method 3015.2 of MIL-STD-883C, the

AD766 has been classified as a Category 1 Device.

Proper ESD precautions are strongly recommended to avoid functional damage or perfor-

mance degradation. Charges as high as 4000 volts readily accumulate on the human body and

test equipment, and discharge without detection. Unused devices must be stored in conduc-

tive foam or shunts, and the foam discharged to the destination socket before devices are

removed. For further information on ESD precaution, refer to Analog Devices’ ESD

Prevention Manual.
