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
AD7711 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.
AD7711–SPECIFICATIONS
The AD7711 is specified with a 10 MHz clock for AV
The ± 5% tolerance on the DV
Measured at dc and applies in the selected pass band. PSRR at 50 Hz will exceed 120 dB with filter notches of 10 Hz, 25 Hz, or 50 Hz. PSRR at 60 Hz will exceed
PSRR depends on gain: Gain of 1 = 70 dB typ; Gain of 2: 75 dB typ; Gain of 4 = 80 dB typ; Gains of 8 to 128 = 85 dB typ. These numbers can be improved (to
95 dB typ) by deriving the V
than 10.5 V. Operating with AV
