NOTES
18
The 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.
19
The
±
5% tolerance on the DV
input is allowed provided that DV
does not exceed AV
by more than 0.3 V.
20
Measured 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.
21
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
voltage (via Zener diode or reference) from the AV
supply.
22
Using the hardware STANDBY pin. Standby power dissipation using the software standby bit (PD) of the Control Register is 8 mW typ.

CAUTION
ESD (electrostatic discharge) sensitive device. The digital control inputs are diode protected;
however, permanent damage may occur on unconnected devices subject to high energy electro-
static fields. Unused devices must be stored in conductive foam or shunts. The protective foam
should be discharged to the destination socket before devices are inserted.
