AD7712–SPECIFICATIONS
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
AD7712 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.

NOTES
18The AD7712 is specified with a 10 MHz clock for AV
DD voltages of +5 V
± 5%. It is specified with an 8 MHz clock for AV
DD voltages greater than 5.25 V and less
than 10.5 V. Operating with AVDD voltages in the range 5.25 V to 10.5 V is guaranteed only over the 0 C to 70 C temperature range.
19The
±5% tolerance on the DV
DD input is allowed provided that DVDD does not exceed AVDD by more than 0.3 V.
20Measured at dc and applies in the selected passband. 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 120 dB with filter notches of 10 Hz, 30 Hz, or 60 Hz.
21PSRR 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 VBIAS voltage (via Zener diode or reference) from the AVDD supply.
22Using the hardware STANDBY pin. Standby power dissipation using the software standby bit (PD) of the Control Register is 8 mW typ.
