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 AD768 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.
Measured at IOUTA, driving a virtual ground.
Nominal FS output current is 4 the current at IREFIN. Therefore, nominal FS current is 20 mA when IREFIN = 5 mA.
Output current is defined as total current available for IREFIN and any external load.
Reference bandwidth is a function of external cap at NR pin. Refer to compensation section of data sheet for details.
Excludes internal reference drift.
Includes internal reference drift.
Measured as unbuffered voltage output (1 V range) with FS current into 50
rating only and functional operation of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating for extended periods may affect device
reliability.
