AGND; Assumes VBIAS Is Fixed Positive Supply (AVDD and DVDD) See Note 19 dB typ Negative Supply (VSS)90 dB typ Power Dissipation Normal Mode 45 mW max AVDD = DVDD = +5 V, VSS = 0 V; Typically 25 mW 52.5 mW max AVDD = DVDD = +5 V, VSS = –5 V; Typically 30 mW Standby (Power-Down) Dissipation 15 mW max AVDD = DVDD = +5 V, VSS = 0 V or –5 V; Typically 7 mW NOTES 16The AD7711 is specified with a 10 MHz clock for AV DD voltages of 5 V ± 5%. It is specified with an 8 MHz clock for AVDD 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 only guaranteed over the 0 ∞C to 70∞C temperature range. 17The ±5% tolerance on the DVDD input is allowed provided DVDD does not exceed AVDD by more than 0.3 V. 18Measured 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 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. Specifications subject to change without notice.

G –4– 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. |
