Stresses above these ratings may permanently damage the device.
NOTES: (1) Hold mode is activated only when pin 12 is low and pin 11 is high.
For normal use with ADC701, pin 12 is grounded and pin 11 is connected to
ADC701 Sample/Hold control (ADC701 pin 15). (2) If the buffer amp is not used,
pin 17 should be grounded. (3) NC = No Internal Connection.
