These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under electrical characteristics and timing characteristics is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. general electrical characteristics over recommended operating free-air temperature range, single-ended input, normal long sampling, 200 KSPS, AVDD = 5 V, VREFP = 4 V, VREFM = 0 V, SCLK frequency = 25 MHz, fixed channel at CONV mode 00, analog input signal source resistance = 25 Ω (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP† MAX UNIT Digital Input VIH High-level digital input voltage DVDD = 5 V 3.8 V VIH High-level digital input voltage DVDD = 3 V 2.1 V VIL Low-level digital input voltage DVDD = 5 V 0.8 V VIL Low-level digital input voltage DVDD = 3 V 0.6 V IIH High-level digital input current VI = DVDD 0.005 2.5 µA IIL Low-level digital input current VI = DGND −2.5 −0.005 µA Input capacitance 20 25 pF Digital Output VOH High-level digital output at 30 pF load Io = −0.2 mA DVDD = 5 V 4.2 V VOH High-level digital output at 30 pF load Io = −0.2 mA DVDD = 3 V 2.4 V DVDD = 5 V Io = 0.8 mA 0.4 VOL Low-level digital output at 30 pF load DVDD = 5 V Io = 50 µA 0.1 V VOL Low-level digital output at 30 pF load DVDD = 3 V Io = 0.8 mA 0.4 V DVDD = 3 V Io = 50 µA 0.1 IOZ Off-state output current VO = DVDD CS = DVDD 0.02 1 µA IOZ Off-state output current (high-impedance state) VO = DGND CS = DVDD −1 0.02 µA Power Supply AVDD Supply voltage 4.75 5 5.5 V DVDD Supply voltage 2.7 5 5.5 V ICC Power supply cur- AVDD current AlCC Conversion clock is internal OSC, AVDD = 5.5 V − 4.5 V, CS = DGND, 4.2 5 mA ICC Power supply cur- rent DVDD current DlCC AVDD = 5.5 V − 4.5 V, CS = DGND, Excluding bipolar input biasing current 1.6 2.0 mA ICC (autopwrdn): Autopower-down power supply For all digital inputs = DVDD or DGND, AVDD = 5.5 V, Excluding bipolar input SCLK OFF 20 µA CC (autopwrdn): Autopower-down power supply current DD AVDD = 5.5 V, Excluding bipolar input biasing current, external reference SCLK ON 175 230 µA Operating temperature −40 85 °C † All typical values are at TA = 25°C. |
