NOTES

16The AD7710 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.

17The

±5% tolerance on the DV

DD input is allowed provided that DVDD does not exceed AVDD by more than 0.3 V.

18Measured 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.

19PSRR 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.

AD7710–SPECIFICATIONS

REV. F

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 AD7710 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.

WARNING!
